Glucose properties Glucose properties What is glucose? Glucose is the most important simple carbohydrate (sugar) . It has a crystalline aspect, it is white and its formula is C6H12O6. It is also known as "r grape sugar " because it appears in very high amounts in must (a 30% of its weight) The plants mainly obtain it through the photosynthesis and animals primarily through the diet. Glucose can also be obtained by decomposition through the action of water (hydrolysis) of other carbohydrates such as starch, cellulose, maltose or glycogen. Glucose is fermented by yeast action producing ethyl alcohol and carbon dioxide. Thus, for example, you get the wine from the grapes. Industrially, it is obtained from starch with use of acids or by the action of the water. It is used as a sweetener in food industry and also in leather and dyes industries. In medicine it is given intravenously to treat dehydration or intravenous feeding. The importance of glucose in the human body Glucose is the source of energy in the body.

Glucose appears in the cells and body fluids, being very important how the body regulates its levels and distribution, which is known as blood sugar or glucose in the blood, blood plasma or serum. In this way glucose is an indicator of how the body regulates glucose content in blood. Glucose levels When levels are above what is considered normal (70 mg / dl and 100 mg / dL) occurs what is known as hyperglycemia, which can be a symptom of a disease, such as diabetes . Glycosuria is the excess of sugar in the urine and can also be a symptom of this disease, but it also manifests itself in healthy people who have ingested too much sugary food. When levels of glucose in the blood are below normal is considered to produce what is known as hypoglycemia (at less than 50-60 mg per 100 mL). This may be due to poor management of insulin in diabetic patients. In healthy people, it is usually due to excessive consumption of glucose produced by very low calorie diets. Hypoglycemia can also occur in cases of alcoholism or people with liver problems.

Croissants, chocolates and pastry are the richest glucose diet sources Metabolism of carbohydrates Glucose is vital to the human body. Most of the carbohydrates ingested through food, directly or processed, end up as glucose. (More information in Metabolism of carbohydrates ) Fruits are high in sugar (mainly fructose ) Glucose or fructose According to recent studies conducted by the Center for Biomedical Research Network-Physiopathology of Obesity and Nutrition (CIBERobn) carried out on animals, prolonged intake of fructose in large amounts increases the body's resistance to insulin, what favors the development of diabetes . Other studies in the United States are on the same line. According to all of them, unlike what was previously thought, fructose is more dangerous than glucose itself since it is able to neutralize the insulin which controls how the sugar is metabolized by the cells. This can lead to the development of many metabolic diseases, including obesity , high cholesterol and triglycerides and insulin-dependent diabetes (type 2) All the studies have concluded that fructose is more dangerous when taken in liquid form than when taken from fresh fruit.

It is therefore not advisable to replace a piece of fruit for a fruit juice, and especially bad is the consumption of soft drinks sweetened with fructose or fructose-sweetened products. (More information on this subject in the page of the properties of the fructose ) Simple or complex sugars It is important to moderate the consumption of foods containing simple sugars, either fructose or table sugar (sucrose) (See simple carbohydrates in the listing above). High consumption of these products may be responsible, as we have seen, not only for the development of obesity, diabetes or triglycerides, but also the emergence of other diseases such as premature aging , heart diseases , osteoporosis , tooth decay , gingivitis , Crohn's diseases , ulcerative colitis , reduced resistance to infectious diseases by weakening the immune system or general fatigue.

Glucose Diffen › Health While fructose and glucose have the same calorific value, the two sugars are metabolized differently in the body. Fructose has a lower glycemic index than glucose but has a much higher glycemic load. Fructose causes seven times as much cell damage as does glucose, because it binds to cellular proteins seven times faster; and it releases 100 times the number of oxygen radicals (such as hydrogen peroxide, which kills everything in sight). [1] Fructose is a simple sugar commonly found in fruits and vegetables . Vast quantities are also manufactured in the lab. Glucose, also known as grape or blood sugar, is present in all major carbohydrates like starch and table sugar. While both are a good source of energy, excess of glucose can be fatal to diabetic patients, and excess of fructose can lead to health problems like insulin resistance and liver disease. Comparison chart Fructose versus Glucose comparison chart Fructose Blood sugar, dextrose, corn sugar, grape sugar Kind of sugar Source of energy. Often added to food and drinks to improve taste. Source of energy. Fuels cellular respiration. Produced by Photosynthesis, the breakdown of glycogen.

Vast quantities produced artificially in the lab by the food industry. Photosynthesis, the breakdown of glycogen. Sources Honey, flowers, berries, most root vegetables. All major carbohydrates α-D-glucose: 146 °C, β-D-glucose: 150 °C CAS number Fruits and vegetables are a natural source of fructose. Calories 1 ounce of fructose contains 104 calories . 1 ounce of glucose contains 110 calories. Effects on the Body Excessive consumption of fructose has been linked to insulin resistance, obesity and non-alcoholic liver disease. Studies suggest that it leads to added fat in the belly, which is linked to an increased risk for heart disease and diabetes. Fructose also leads to higher cholesterol. Studies suggest that fructose lowers activity in the cortical control areas of the brain. An excessive amount of glucose in the blood can be fatal. However, this only occurs in diabetic individuals when their pancreas does not release enough insulin into the bloodstream. Most fat gained from excessive intake of glucose is subcutaneous, or under the skin, which is not connected to heart disease or diabetes . Glucose is not linked to insulin resistance or higher cholesterol.

Studies suggest that the consumption of glucose significantly raises the level of activity in the brain. In a recent study conducted by Lane MD at Johns Hopkins University School of Medicine in Baltimore,US revealed that: Fructose increases food intake whereas glucose decreases food intake. This is because glucose leads to an increase in hypothalamic ATP which gives rise to a suppression of food intake. Whereas fructose requires an enzyme that requires ATP, which causes ATP depletion thereby giving rise to an increase in food intake. The rise in consumption of high-fructose sweeteners, soft drinks and corn syrup parallels the rise in the obesity epidemic . High fructose diets promote insulin resistance and glucose intolerance which increases the rate of hepatic lipogenesis. On a average Americans consume 140lbs of high fructose sweeteners per year, of which 77lbs is high fructose corn syrup . Beneficial uses in the human body Fructose is used in respiration to produce ATP and to build glycogen. It can also produce fat to store energy . Cells also use glucose to fuel respiration . It is also used in Vitamin A production and for the synthesis of several substances, including starch and glycogen.

Sources of fructose and glucose Fructose is naturally found in most fruits and vegetables (including sugar cane) and honey. Foods that contain table sugar, high-fructose corn syrup, agave nectar , maple syrup and fruit juice also contain fructose. All major carbohydrates contain glucose. Examples include starch and table sugar. Commercial use Fructose is commercially added to many foods and beverages as a low cost sweetener. High fructose corn syrup is often added to processed food and drinks is the United States as a cheap sweetener, and has been the subject of many controversies, as it is allegedly associated with obesity , cardiovascular disease, diabetes and non-alcoholic fatty liver disease . Glucose is also used as a sweetener in the form of corn syrup. Relative sweetness of various sugars and sweeteners Production Fructose is produced by plants during photosynthesis . Glucose is naturally produced during photosynthesis in plants or during the breakdown of glycogen. It is also produced commercially through the enzymatic hydrolysis of starch. References glucose, also known as blood sugar, has the molecular formula C6H12O6.

why can glucose not be represented with a formula unit of CH2O | eNotes glucose, also known as blood sugar, has the molecular formula C6H12O6. why can glucose not be represented with a formula unit of CH2O trophyhunter1 | College Teacher | (Level 1) Educator Emeritus Posted on March 5, 2012 at 7:06 AM CH2O is a general formula for any carbohydrate. One can recognize a carbohydrate because the ratio of hydrogen atoms to oxygen atoms is 2:1 as in the formula CH2O. However, when one specifically looks at different carbohydrates like glucose(monosaccharide), maltose(disaccharide) or starch(polysaccharide), the number of atoms will differ changing the formula. However, there will always be twice as many hydrogen atoms as oxygen. If you look at the formula for glucose, it is C6H12O6. The least common denominator is 6. If you divide the 12 Hydrogen atoms in the equation by 6, the result is 2. If you divide the 6 oxygen atoms by 6, the result is 1.

The 2:1 oxygen ratio is there, in the formula! Therefore, it fits with the general rule for recognizing a formula that represents carbohydrates. Every sugar will have its own molecular formula.

You can also browse the list of common chemical compounds . ›› More information on molar mass and molecular weight In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. The atomic weights used on this site come from NIST, the National Institute of Standards and Technology.

We use the most common isotopes. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation are sometimes called equation weights. Finding molar mass starts with units of grams per mole (g/mol). When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.

Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. A common request on this site is to convert grams to moles . To complete this calculation, you have to know what substance you are trying to convert. The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass. This page was loaded in 0.003 seconds.

Glucose is a normal component of animal blood; it thus requires no digestion prior to absorption into the bloodstream.

Glucose can be obtained by hydrolysis hydrolysis , chemical reaction of a compound with water, usually resulting in the formation of one or more new compounds. The most common hydrolysis occurs when a salt of a weak acid or weak base (or both) is dissolved in water. .....

Glucose is used in the manufacture of candy, chewing gum, jams, jellies, table syrups, and other foods, and for many other purposes. It is the major source of energy in animal metabolism.

Glucose tastes only about three-fourths as sweet as table sugar ( sucrose sucrose , commonest of the sugars, a white, crystalline solid disaccharide (see carbohydrate) with a sweet taste, melting and decomposing at 186&degC; to form caramel.

Glucose A monosaccharide also known as d -glucose, d -glucopyranose, grape sugar, corn sugar, dextrose, and cerelose. The structure of glucose is shown in the illustration.

Structural formula for α- D -glucose Glucose in free or combined form is not only the most common of the sugars but is probably the most abundant organic compound in nature. It occurs in free state in practically all higher plants. It is found in considerable concentrations in grapes, figs, and other sweet fruits and in honey. In lesser concentrations, it occurs in the animal body fluids, for example, in blood and lymph. Urine of diabetic patents usually contains 3–5%. Cellulose, starch, and glycogen are composed entirely of glucose units. Glucose is also a major constituent of many oligosaccharides, notably sucrose, and of many glycosides. It is produced commercially from cornstarch by hydrolysis with dilute mineral acid. The commercial glucose so obtained is used largely in the manufacture of confections and in the wine and canning industries. See Glycogen d -Glucose is the principal carbohydrate metabolite in animal nutrition; it is utilized by the tissues, and it is absorbed from the alimentary tract in greater amounts than any other monosaccharide. Glucose could serve satisfactorily in meeting at least 50% of the entire energy needs of humans and various animals.

Glucose enters the bloodstream by absorption from the small intestine. It is carried via the portal vein to the liver, where part is stored as glycogen, the remainder reentering the circulatory system. Another site of glycogen storage is muscle tissue. Glucose is readily fermented by yeast, producing ethyl alcohol and carbon dioxide. It is also metabolized by many bacteria, resulting in the formation of various degradation products, such as hydrogen, acetic and butyric acids, butyl alcohol, acetone, and many others. See Carbohydrate , Monosaccharide Glucose (grape sugar, dextrose), the carbohydrate most frequently found in nature; it belongs to the hexoses, that is, to monosaccharides containing six carbon atoms. Its crystals are colorless, and its melting point is 146.5° C. It is highly soluble in water. Glucose solutions contain molecules in the α- and β- forms; equilibrium is attained at 37 percent and 63 percent, respectively, of these forms. Glucose is optically active, bending a beam of polarized light to the right.

Glucose of the α-form is an essential component of all living organisms, from viruses to higher plants and vertebrates (including man). It is a component of various compounds, ranging from saccharose, cellulose, and starch to some glycoproteins and viral ribonucleic acid. For a number of bacteria, glucose is the only source of energy. Glucose participates in many metabolic reactions. The glucose content of human blood is about 100 mg percent, and it is regulated by the neurohumoral mechanism. A lowering of the glucose content to 40 mg percent leads to a sharp disturbance of the activity of the central nervous system. The basic means of glucose utilization in the organism are anaerobic transformations, accompanied by the ATP synthesis and terminating in the formation of lactic acid; glycogen synthesis; aerobic oxidation to gluconic acid in the presence of glucoseoxydase, a process occurring in some microorganisms that utilize it to produce energy and accompanied by oxygen absorption from the air; and the conversion of glucose to pentoses and other simple sugars.

The complete enzymatic oxidation of glucose to CO2 and H2O is accompanied by the release of energy: C6H12O6 + 602—6CO2 + 6H2O + 686 kilocalories per mole. Most of this energy is accumulated by high-energy compounds of the ATP type. The synthesis of glucose from inorganic components is the reverse process, carried out by plants and some bacteria using the energy of sunlight (photosynthesis) and the energy of chemical oxidation reactions (chemosynthesis). Glucose is produced industrially by starch hydrolysis. It is used in the pastry industry and medically as a drug. A. A. B OLDYREV Glucose is used for medical purposes in powder and tablet form, as well as in isotonic (4.5-5 percent) and hypertonic (10-40 percent) glucose solutions. Isotonic solutions are administered (subcutaneously and in enemas) for replacing fluid in the organism. These solutions are also a source of readily assimilable nutrients.

Introduction of hypertonic solutions (intravenously) leads to an increase in the osmotic pressure of the blood, improves the metabolic processes, strengthens the antitoxic function of the liver and the contractive activity of the heart muscles, dilates the blood vessels, and increases the elimination of urine. Glucose solutions are used to treat infectious diseases, heart ailments, various intoxications, and other conditions, frequently in combination with ascorbic acid. REFERENCE Biochemistry/Carbohydrates - Wikibooks, open books for an open world Biochemistry/Carbohydrates Introduction[ edit ] "Carbohydrates" are chemically defined as "polyhydroxy aldehyde or polyhydroxy ketones or complex substances which on hydrolysis yeild polyhydroxy aldehyde or polyhydroxy ketone." Carbohydrates are one of the fundamental classes of macromolecules found in biology . Carbohydrates are commonly found in most organisms, and play important roles in organism structure, and are a primary energy source for animals and plants. Most carbohydrates are sugars or composed mainly of sugars. By far, the most common carbohydrate found in nature is glucose, which plays a major role in cellular respiration and photosynthesis.

Some carbohydrates are for structural purposes, such as cellulose (which composes plants' cell walls) and chitin (a major component of insect exoskeletons). However, the majority of carbohydrates are used for energy purposes, especially in animals. Carbohydrates are made up of a 1:2:1 ratio of Carbon, Hydrogen, and Oxygen (CH2O)n Simple Carbohydrates (Monosaccharides)[ edit ] These are used only for energy in living organisms. Simple carbohydrates are also known as "Monosaccharides".The chemical formula for all the monosaccharides is CnH2nOn. They are all structural isomers of each other. There are two main types of monosaccharides. The first type are aldoses, containing an aldehyde on the first carbon, and the second type are ketoses, which have a ketone on the second carbon (This carbonyl group is always located on the second carbon).

Name Formula Aldoses Ketoses Trioses C3 H6 O3 Glycerose Dhydroxyacetone Tetroses C4 H8 O3 Erythrose Erythrulose Pentoses C5 H10 O5 Ribose Ribulose Hexoses C6 H12 O6 Glucose Fructose Heptose C7 H14 O7 Glucoheptose Sodoheptulose The suffix -oses is kept for the aldoses & the suffix -uloses is kept for the ketoses. Except fructose ketoses are as common as aldoses.The most abundant monosaccharide in nature is the 6-Carbon sugar -i.e.D-Glucose. All aldoses are reducing sugars. Many ketoses are also considered reducing sugars because they can isomerise to aldoses. Monomers[ edit ] There are two main forms of monomer, aldoses and ketoses, of which, all have the same backbone. The simplest for of monomers are trioses. The trioses consist of three carbons in the backbone.

Fructose[ edit ] Fructose is a ketohexose with the molecular formula of C6H12O6 ; which is same as the molecular formula of Glucose but different structure. The structure of fructose differs from glucose at carbon 1 and 2 by the location of the carbonyl group. Fructose is the sweetest naturally occurring sugar. Fructose is also called levulose and fruit sugar; fructose is also found in fruits, root vegetables(such as sweet potato and onion) and honey. It is a isomer of glucose and a ketose simple sugar. Fructose has the highest solubility among all sugars. Fructose can be converted to its isomer glucose, after it enters the blood stream. CH2OH C=O OH-C-H Galactose[ edit ] Galactose is a sugar component of the disaccharide lactose, as found in milk. It is not as sweet as glucose and is separated from the glucose in lactose via hydrolysis.In addition, galactose is an aldohexose that does not occur in the free form in nature; galactose has an important role in the cellular membrane of the brain and nervous system.

D-galactose has a structure similar to D-glucose and the only difference between them is in the arrangement of the –OH group on carbon number 4. Galactose can be found in human breast milk and is incorporated into the structure of Human Milk Oligosaccharides. The backbone of Human Milk Oligosaccharides is the disaccharide lactose, which is formed by the linkage between galactose and glucose sugars.. Oligosachharides Tha oligosachharides yields 2 to 10 monosachharides on hydrolysis. Disachharides are most common oligosachharide found in nature. Disaccharides[ edit ] Monosaccharides are simple forms of sugars consisting of one sugar, disacharides on the other hand, consists of two. The two sugars are bonded together via a glycosidic bond. Most linkages between sugars occur between the first and fourth carbon on the sugars. Polysaccharides[ edit ] Sugars do not stop at disaccharides, they are much more complex than that. Multiple sugars are linked together forming many polysaccharides.

Polysaccharides are made up of monosaccharides linked together. Compound Carbohydrates (Disaccharides)[ edit ] These are used by living organisms for energy. They are composed of two monosaccharides joined together by the process known as dehydration synthesis. In this process, one molecule loses one hydrogen atom, while the other loses one hydrogen atom and one oxygen atom. The reverse of this is hydrolysis, where water is added to break down a molecule into two or more simpler molecules. Disaccharides have the chemical equation C12H22O11. The reason it does not follow the 1:2:1 ratio is, obviously, due to the H2O taken way from it.

Some examples of disaccharides are: Disachharides Non reducing reducing C1-C1 glycosidic C1-C2 glycosidic C1-C4 glycosidic C1-C6 glycosidic linkage linkage linkage linkage Trehalose Sucrose Lactose Gentiobiose Maltose Melibiose Cellobiose Isomaltose Maltose[ edit ] Chemistry- Maltose is a white crystal sugar, also known as malt sugar and a reducing disaccharide made from two glucose units. The bonding of two glucose units is called 1-4 glycosidic linkage which joins the carbon number 1 of one glucose to carbon number 4 of the second glucose.In the presence of enzyme maltase,1-4 linkage of two glucose is broken down and maltose is hydrolized into glucose occurrence- Maltose is present in sprouting barley. It is the major product of hydrolysis of starch. alpha - maltose Sucrose[ edit ] 3Occurrence- It is the costituent of sugarcane. it is also found in Beet,carrot,etc. Nector of flower is particularly rich in sucrose.

3Chemistry- Sucrose is white crystal sugar.When heat above its melting point it forms a brown substance known as "Caramel". it is non reducing sugar. Sucrose is formed by the C1-C2 glucosidic bond between glucose & fructose. Sucrose on hydrolysis yield equimolar mixture of glucose & fructose which is offen called as "invert sugar" by the "enzyme". Lactose[ edit ] 3 Occurrence- It is found in milk of animal. It is also Milk sugar. The percentage of latose in human milk is 6.8 % & in cow milk is 4.8 % 3 Chemistry- Lactose is made by the C1-C4 glycosidic bond between galactose & glucose. The hydrolysis of Lactose gives the monosacchride: glucose + glactose by the enzyme lactase. Lactose can be a reducing sugar. β-D-galactopyranosyl-(1→4)-D-glucose The molecular structure of α-lactose, as determined by X-ray crystallography.

Complex Carbohydrates (Polysaccharides)[ edit ] Polysaccharides, also called as glycanes, are high molecular weight which on hydrolysis yield monosaccharides. Some sources of complex carbohydrates are pasta, bread, rice, cereals, crackers, corn, beans, potatoes, pumpkin, and peas. Digestion of complex carbohydrates could take more time because digestive enzyme have to work harder to break down the chain into individual sugars. Complex carbohydrates contain hundreds of sugar units. Studies show that glucose levels both rise and fall more slowly after the consumption of bread compared to sugars or fruit, suggesting slower digestion. [1] Both monosaccharides and disaccharides are used only for energy. Another difference is that while monosaccharides and disaccharides can be used for energy immediately, polysaccharides release their energy slowly. Research shows that the carbohydrate oxidation rate rises more slowly after the consumption of bread rather than sucrose following an overnight fast. The carbohydrate oxidation rate is also lower over a six-hour period following the consumption of bread in lieu of sucrose. [2] Chemically , the polysaccharide may be distinguished into homopolysachharide & heteropolysachharide.

Homopolysachharides which on hydrolysis yield only single monosachharide. Eg. starch, cellulose, etc. Hateropolysachharide which on hydrolysis yield two or more monosaccharide. Eg. heparin, chondroitin, etc. POLYSACHHARIDE Homopolysachharide Heteropolysachharide Starch Mucopolysachharids Glucogen Chondroitin Inulin Hyaluronic acid Cellulose Keratosulfate Pectin Heparin Chitin Vegetable gum Xylan Agar agar polysachharide may be classified on the basis of functional aspect as Nutritive & Structural. Nutritive- starch,glycogen,inulin etc. Structural- cellulose,chitin,pectin,etc. Cellulose (Fiber)[ edit ] Cellulose is a special kind of carbohydrate. It is insoluble and most organisms can not produce enzymes to break it down. It is made by β-D-glucose. It is found only in plants, and it's found in the cell wall. It is composed of β glucose molecules, which create a more rigid structure.

Cotton used to make clothes etc. is cellulose from around the seeds of the cotton plant. Fibre helps the plant keep a strong structure. Humans can't digest fibre.it gives no color with iodine.It is completely absent in meat, egg, fish & milk. Starch[ edit ] Starch is the energy storage molecule of plants.It is formed by long chains of α glucose molecules linked together. It is mostly found in potato. Starch is actually a mixture of 2 types of molecules, amylose and amylopectin. These large polysaccharides are very good for energy storage because they have lots of glucose molecules crammed into a small space which can then be easily broken off, one at a time, by hydrolysis and then used for energy. It is hydrolysed by enzyme Amylase.It is non reducinh sugar. It gives blue,purple colour with iodine Glycogen[ edit ] Glycogen is the energy storage molecule of animals. It is formed by branched chains of alpha glucose molecules with 1-4 glycosidic bonds on the main chains and 1-6 glycosidic bonds to form the branches. Humans store small amounts of glycogen in the liver and muscles.

It is created when there are high blood sugar levels. The pancreas secretes insulin, which stimulates the creation of glycogen from glucose and signals the body to use glucose as its main form of energy. It is non reducing sugar. It gives red colour with iodine. References[ edit ] ↑ Wolever, Thomas M. S.

What is the chemical name for C6H12O6? | Reference.com What is the chemical name for C6H12O6? A: Quick Answer Chemical compounds with the molecular formula C6H12O6 are known as hexoses. Common examples of hexoses include glucose, fructose and galactose. Compounds with the same molecular formula but vary in structural formulas are referred to as structural isomers. Full Answer Carbohydrates, also called sugars or saccharides, constitute one of the essential biomolecules in living organisms. Sugar compounds are comprised of three main elements, which include carbon (C), hydrogen (H) and oxygen (O). The general formula for all carbohydrates is CxH2yOy, where "x" denotes the number of carbon atoms, "2y" indicates the number of hydrogen atoms and "y" represents the number of oxygen atoms. Carbohydrates are classified into three types: monosaccharides, disaccharides and polysaccharides. Monosaccharides are the simplest form of carbohydrates, which contain only a single sugar molecule.

A 3-carbon monosaccharide, such as glyceraldehyde, is called a "triose," while a 5-carbon monosaccharide, such as deoxyribose, is known as a "pentose." A 6-carbon monosaccharide is referred to as a "hexose." Glucose, otherwise known as "blood sugar" or "dextrose," is the bio-fuel used in cellular respiration and the source of usable energy for most organisms. It is commonly found in fruits and vegetables. Fructose, or fruit sugar, is the sweetest among all sugar compounds. It is typically found in fruits and honey. Galactose is an important component in glycolipids and glycoproteins, although it rarely exists in nature. Glucose, Glucose Glucose, Glucose This parody (written by Greg Crowther) is sung to the tune of "Sugar, Sugar" (written by Jeff Barry and Andy Kim and performed by The Archies). Context Glucose is a six-carbon sugar represented by the formula C6H12O6.

Glucose is vital to the functioning of many of the body's cells, including muscle cells, because it yields energy in the form of ATP when it is broken down. Through a series of reactions known collectively as glycolysis, glucose is converted to a three-carbon molecule known as pyruvate. The pyruvate can then be further processed by the mitochondria to produce carbon dioxide and water. If pyruvate is being formed faster than it is being utilized, three-carbon molecules accumulate in the form of lactic acid (lactate). A buildup of lactic acid due to "excessive" glucose breakdown is thought by some to impair exercise performance. In addition, a lack of glycogen (the storage form of glucose) is also thought to cause fatigue under some circumstances. Thus, many athletes have what might be termed a "love-hate relationship" with glucose: they need it to fuel their muscles during exercise, yet burning it at high rates can get them into trouble. This song probes the nature of this relationship and includes a cameo appearance by the lactate molecule itself, which sings the line, "I'm gonna make your muscles ache," shown in italics.

(This line is an allusion to the now-discredited hypothesis that lactic acid causes muscle soreness.) Lyrics You are my favorite fuel From the blood-borne substrate pool. Glucose -- monosaccharide sugar -- You're sweeter than a woman's kiss 'Cause I need you for glycolysis. I just can't believe the way my muscles take you in. (For you, they'll open the door.) All it takes is a little bit of insulin (To upregulate GLUT4). Ah, glucose -- ah, sugar sugar -- You help me make ATP When my predators are chasing me. Ah, glucose -- you're an aldehyde sugar, And you're sweeter than a woman's kiss 'Cause I need you for glycolysis. I just can't believe the way my muscles break you down. (My glycogen is almost gone.) A few more seconds and I'll be rigor mortis-bound. (Acidosis done me wrong.) Your sweet is turning sour, baby. I'm losing all my power, baby. I'm gonna make your muscles ache. No, no, no! I'm swimming in lactate, baby. Yes, I'm swimming in lactate, baby.

Now I'm drowning in lactate, baby. I'm gonna make your muscles ache. No, no, no! I'm drowning in lactate, baby. Ah, glucose -- ah, sugar sugar -- I used you up and you left me flat; Now I'll have to get my kicks from fat. Oh, glucose, glucose, sugar, sugar, The honeymoon is over now. Other Files Sugars Glucose Glucose is a carbohydrate , and is the most important simple sugar in human metabolism. Glucose is called a simple sugar or a monosaccharide because it is one of the smallest units which has the characteristics of this class of carbohydrates. Glucose is also sometimes called dextrose. Corn syrup is primarily glucose. Glucose is one of the primary molecules which serve as energy sources for plants and animals. It is found in the sap of plants, and is found in the human bloodstream where it is referred to as "blood sugar". The normal concentration of glucose in the blood is about 0.1%, but it becomes much higher in persons suffering from diabetes.

When oxidized in the body in the process called metabolism, glucose produces carbon dioxide, water, and some nitrogen compounds and in the process provides energy which can be used by the cells. The energy yield is about 686 kilocalories (2870 kilojoules) per mole which can be used to do work or help keep the body warm. This energy figure is the change in Gibbs free energy ΔG in the reaction, the measure of the maximum amount of work obtainable from the reaction. As a primary energy source in the body, it requires no digestion and is often provided intravenously to persons in hospitals as a nutrient. Energy from glucose is obtained from the oxidation reaction C6H12O6 + 6O2 --> 6CO2 + 6H2O where a mole of glucose (about 180 grams) reacts with six moles of O2 with an energy yield ΔG = 2870 kJ. The six moles of oxygen at STP would occupy 6 x 22.4L = 134 liters.

The energy yield from glucose is often stated as the yield per liter of oxygen, which would be 5.1 kcal per liter or 21.4 kJ per liter. This energy yield could be measured by actually burning the glucose and measuring the energy liberated in a calorimeter. But in living organisms, the oxidation of glucose contributes to a series of complex biochemical reactions which provides the energy needed by cells. The first step in the breakdown of glucose in all cells is glycolysis , producing pyruvate which is the starting point for all other processes in cellular respiration . In cells where oxygen is present ( aerobic respiration ) these processes have been modeled in the TCA or Krebs cycle . A major part of the use of the energy from glucose oxidation is the conversion of ADP to ATP , with the energy-rich molecule ATP being subsequently used as the energy currency of the cell. Glucose is manufactured by plants with the aid of energy from the sun in the process called photosynthesis . This synthesis is carried out in the small energy factories called chloroplasts in plant leaves. The chloroplasts capture the energy from light and fabricate glucose molecules from carbon dioxide from the air and water from the soil.

Glucose can also be found in a linear form. The right end of this molecule shows the form of an aldehyde . Go Back Comparison of Glucose and Fructose Glucose and fructose are the two most important simple sugars for human consumption. They have the same molecular formula, C6H12O6, but have different structures. Each is a carbohydrate which can be considered to be the combination of 6 water molecules and 6 carbon dioxide molecules with the yield of 6 oxygen molecules. They are classified differently as hydrocarbon derivatives , glucose being classified as an aldehyde and fructose as a ketone . The sugars differ in the bond environment of the oxygen atom in the sugar. The differences in the functional groups can be seen more clearly in the linear forms below. Go Back Cellulose Cellulose is a form of carbohydrate in which some 1500 glucose rings chain together. It is the chief constituent of cell walls in living organisms. Wood is mostly cellulose, making cellulose the most abundant type of organic compound on the Earth. Cellulose molecules tend to be straight chains, and the fibers which result from collections of cellulose molecules have the strength to form the supporting structures of plants.

Even though human digestion cannot break down cellulose for use as a food, animals such as cattle and termites rely on the energy content of cellulose. They have protozoa and bacteria with the necessary enzymes in their digestive systems. Cellulose in the human diet is needed for fiber.
