message: Working with WikiProject Grocer's Encyclopedia, I found historical terms Commercial Glucose, Corn Syrup, Commercial Dextrose, Corn Sugar [] (search for those terms). Would someone be able to incorporate the information found there into the article. I believe the information would be out of date, but it would interesting to add the history of sugar manufacturing and/or vocabulary used in the 1910's.

message: Is L-glucose sweet? and if so can it make you fat?
: I googled "L-glucose taste" for you and came up with this article. According to it, there is no difference in taste between L- and D-glucose, it also won't make you fat because the body can't metabolize L-glucose, so someone thought of the idea of using it as a low calorie sweetner, unfortunately according to the article its very hard to synthesise in the large quantities needed. K.murphy 21:33, 4 June 2007 (UTC)
replies: text:  Also, bear in mind that there are no bugs in your gut that can metabolize L-glucose (precious few can), and it is less sweet than sucrose, so it would be just like taking lactulose every day. Compare the experience of the character in House M.D. (S02E06) who gave up smoking and developed intractable diarrhoea. Greg of course straight away zeroed in on his replacement habit of chewing sugar-free gum, in liberal quantities -  the xylitol in the gum  was giving him the squits.  L-glucose would be worse.

message: Apparently there has been a great deal of confusion as far as the various structures of glucose are concerned... While all the structures shown in the various images are correct, they are randomly scattered throughout the article. This makes it difficult to find the structure being described in the text at any given point. What is needed is a clear diagrammatic representation of the interconversion between the straight chain form (Fischer projection) and the alpha and beta cyclic pyranose forms. (An example of what I'm describing can be found in McMurry: Organic Chemistry, pg.985.) Also apparently absent from the article are the Haworth projections. I'm rather surprised that such an important article is so disorganized... why hasn't this become a featured article yet? Perhaps because it's rather confusing for the average, non-technical reader.

message: If somebody has a low blood sugar, they might be given glucose but if given IV it is most likely to be referred to as "dextrose" rather than "glucose".  In the US, there is perhaps some excuse for this, as the USP and the FDA both seem to prefer the term "dextrose", and that is what it says on infusion labels.  In the UK, the approved name is "glucose", but "dextrose" is widely used informally, and even in official documents (eg: Guidelines on intravenous fluid therapy for surgical patients at www.bapen.org.uk/pdfs/bapen_pubs/giftasup.pdf).  To me, this seems utterly redundant - but can anyone say how or why it came about?  What reason might anyone have for preferring "dextrose" over "glucose"? Moletrouser (talk) 15:16, 20 March 2012 (UTC)
replies: text: Medicine perpetuates a lot of history obsolete in other sciences. Once upon a time the two main monosaccharides in nature were distinguished by their light rotatory powers. Dextrose rotated polarized light to the right and levulose to the left. Levulose has since been renamed fructose but the old term for glucose hung on when given IV. That's the only place the term is still used. It's sort of like a drug brandname now. Doctors give you dextrose but they measure glucose levels in your blood. Pure tradition. Like military terms. Hat vs cover or rifle vs gun. All professions have a few. SBHarris 08:31, 24 November 2012 (UTC)
replies: text: IRC dextrose is defined as a sugar solution specified within a particular range of optical rotations, whereas glucose is defined as glucose. The point is that dextrose isn't necessarily very pure, and may be a mixture of sugars, like has a bit of fructose, provided it measures in the right optical rotation range. So that's why you give dextrose, but measure glucose.Teapeat (talk) 09:16, 24 November 2012 (UTC)
replies: text: That may be true in other industries but not in the pharm industry. The U.S.P. specially defines dextrose as glucose monohydrate crystal. Such reagents are very helpful in preparing IV preps especially with deliquescent solids. For example MgSO4 is prepared as exactly 50% w/v of the heptahydrate, which is why it has the odd concentration of 2.03 meq/ml. In the case of USP D5W it's made up as 5% w/v USP dextrose in water, not glucose! It's only 4.54% w/v glucose, I kid you not. I've been a physician almost 30 years and didn't know that "D5W" would only be "G4.5W".  Anyway outside USP (and apparently some other agencies in Europe) dextrose and glucose are used completely interchangeably. But that one water molecule of hydration has helped to slow that terminological equivalence down in pharmacology. You learn something every day. SBHarris 20:38, 24 November 2012 (UTC)

replies: text: Incorrect statements in the article, thereby endangering the lives of corn-allergic consumers/patients.  In our corn allergy support groups of over 12K members (including many nurses, one retired physician, and a pharmacist), we remain frustrated by the lack of knowledge of medical professionals about the source of dextrose (cornstarch).  One physician actually told a patient that "No one can be allergic to dextrose," and another physician told a corn-allergic patient that she couldn't be allergic to dextrose because "Dextrose is in our bodies." These physicians then administered corn sugar (dextrose) IV fluid to these patients in direct violation of the contraindication warning in the package insert which caused severe allergic reactions requiring emergency intervention.   
Throughout this article, blood sugar (glucose) is being erroneously equated with corn sugar (dextrose). As I clarified in my initial comments, glucose (blood sugar) and dextrose (corn sugar) may be biochemically identical; however, not in relation to their allergenicity; e.g., blood sugar cannot provoke and allergic response, whereas corn sugar can prove fatal to anyone with an IgE-mediated allergy to corn.  For further clarification, glucose (blood sugar) is a natural form of sugar in living organisms; however, since dextrose (corn sugar) is a manufactured sugar from cornstarch, it cannot be found naturally in any food, drug, or biologic product.  
"The naturally occurring form of glucose is D-glucose."  This refers to dextrose (corn sugar) which is not naturally occurring, but is manufactured from cornstarch.
"Glucose, as intravenous sugar solution. . ."  This refers to IV fluids to which corn sugar (dextrose) has been added, and therefore are contraindicated for administration to corn-allergic patients.  Glucose (blood sugar) is not added to intravenous solutions; however, dextrose (corn sugar) is added to some IV solutions, which is why contraindication warnings are listed in the package insert for administration to corn-allergic patients.
Excerpt from my blog addressing this issue:
"CRITICAL UPDATE, AUGUST 6, 2020
A member of one of our corn allergy groups just discovered that corn sugar (dextrose) IV fluid sold outside of the United States by Baxter Healthcare Ltd is labeled as “Glucose 5% Intravenous Infusion BP.”  It is clearly corn sugar (dextrose) IV fluid, since the product information sheet does include contraindication warnings for administration to corn-allergic patients.  Since glucose is blood sugar, physicians may not realize that this product is actually corn sugar (dextrose) IV fluid, thus potentially endangering the lives of corn-allergic patients. 
I placed an emergency call to Baxter Quality Control Department this morning, 1-800-437-5176; and they are taking this matter very seriously.  They are expediting our concerns about the labeling of this product.  I also forwarded corn allergy documentation to them, @baxter_intl, in addition to @Datapharm for their review and consideration."

"Glucose can be obtained by hydrolysis of carbohydrates such as milk sugar (lactose), cane sugar (sucrose), maltose, cellulose, glycogen, etc. It is commonly commercially manufactured from cornstarch by hydrolysis via pressurized steaming at controlled pH in a jet followed by further enzymatic depolymerization."
Corn sugar (dextrose) is manufactured from cornstarch -- not glucose (blood sugar).
In addition, if you research "dextrose" on Wikipedia, the reader is erroneously redirected to "glucose."  If medical professionals are relying on Wikipedia as a source of correct information regarding glucose (blood sugar) vs. dextrose (corn sugar), this could explain why the lives of corn-allergic patients are in constant danger.  As a result, we are required to carry critical corn allergy documentation with us at all times to present to medical staff.DextroseIsCornSugar (talk) 14:39, 21 August 2020 (UTC)

Glucose (blood sugar) 
Glucose is blood sugar, and is the "main sugar that the body manufactures [and] serves as the major source of energy for living cells." 
Since glucose is blood sugar, it cannot be categorized as an independent ingredient in any food, drug, or biologic product.  The false narrative of equating glucose (blood sugar) with dextrose (corn sugar) appears to have been initiated by the corn industry decades ago. 
Dextrose (corn sugar) 
Dextrose is corn sugar manufactured from cornstarch per Code of Federal Regulation 21CFR184.1857, Sec. 184.1857. 
It is for this reason that intravenous solutions to which corn sugar (dextrose) has been added are contraindicated for administration to corn-allergic patients.       
The confusion about these two sources of sugar has resulted in false and misleading references on the Internet, thereby endangering the lives of corn-allergic consumers and patients.
"Glucose also known as dextrose . . ."
Glucose (blood sugar) is not dextrose (corn sugar), and dextrose (corn sugar) is not glucose (blood sugar). 
“Dextrose is also naturally found in fruits, honey and grains.”
It is impossible for dextrose (corn sugar manufactured from cornstarch) to be found naturally in any food/drug/biologic product. 
"Simple sugars, including dextrose, fructose, and glucose, appear in foods such as table sugar, honey, and bread."
It is impossible for dextrose (corn sugar manufactured from cornstarch) to be found naturally in any food/drug/biologic product. 
“Dextrose (glucose) is a form of natural sugar that is normally produced by the liver.” 
Dextrose (corn sugar manufactured from cornstarch) is not glucose, is not natural, and is not produced by the liver. 
"Dextrose  . . . is made from corn (plus sometimes other veggies)."
The only source of dextrose is corn per Code of Federal Regulation 21CFR184.1857 which is why dextrose is contraindicated for anyone with an IgE-mediated allergy to corn. 
"When dextrose is injected, it feeds your body’s cells with glucose."
When dextrose is injected, it feeds your body’s cells with “corn sugar” – not glucose (blood sugar). 
“Although dextrose is derived from plants and is considered a "natural" product. . . “
The only source of dextrose is corn, and it is manufactured from cornstarch; therefore, it is not “natural.” 
“(Redirected from Dextrose)”
Wikipedia erroneously redirects the reader to “Glucose” if “Dextrose” is searched. 
“Dextrose is . . . found in many everyday food items such as . . . honey.”
Since dextrose is corn sugar manufactured from cornstarch, it’s impossible for dextrose to be found “naturally” in honey. 
“. . . found in plants and animals and in human blood, and made by the hydrolysis of starch with acids or enzymes.”

message: Numerous online publications erroneously assert that glucose (blood sugar) and dextrose (corn sugar manufactured from cornstarch)  are identical (or nearly identical), thereby endangering the lives of corn-allergic consumers and patients.       
The molecular weights of the following two compounds are not identical.  Therefore, which one of these molecular formulas represents straight blood sugar (glucose): the "main sugar that the body manufactures [and] serves as the major source of energy for living cells?”  It is clear that the definition of glucose (blood sugar) by Dr. William C. Shiel, Jr. supports the fact that glucose (blood sugar) cannot be equated with corn sugar manufactured from cornstarch (dextrose), since our body does not manufacture corn sugar (dextrose).

Dextrose is corn sugar that is ADDED TO these products.  Therefore, it is impossible for corn sugar manufactured from cornstarch (dextrose) to be naturally present in grapes/grape sugar.

Does the public have the right to request the "source" of the "Depositor-Supplied Synonym" from the NIH National Library of Medicine for "grape sugar" that is listed in PubChem CID 79025? 
I have personally supplied the NIH National Library of Medicine with the Code of Federal Regulation 21CFR184.1857 which documents that dextrose is corn sugar manufactured from cornstarch. [https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?fr=184.1857
] However, corn sugar is not included in the list of "Depositor-Supplied Synonyms" on either PubChem CID 79025 or PubChem CID 66370.  
Conclusion:
Based on this documentation, it is apparent that the NIH National Library of Medicine is complicit in propagating the false narrative about the source of dextrose (corn sugar manufactured from cornstarch) that was initiated by the corn industry decades ago  with no regard for the safety of corn-allergic consumers and patients."DextroseIsCornSugar (talk) 16:56, 6 September 2020 (UTC)
thread_title:  Grape sugar should not be referenced in this article. 

message: Glucose (blood sugar) must never be equated with dextrose (corn sugar manufactured from cornstarch).  I have supplied the requisite documentation in my August 21, August 23, August 30, and September 6 updates.  
Again, blood sugar (natural) is not to be equated with corn sugar (manufactured from cornstarch).  To equate these two distinct forms of sugar endangers the lives of corn-allergic consumers/patients. 
Again, glucose (blood sugar) is never added to intravenous sugar solutions; because glucose is not an independent ingredient.  Intravenous solutions to which dextrose (corn sugar manufactured from cornstarch) has been added are clearly contraindicated for administration to corn-allergic patients. Glucose (blood sugar) cannot provoke an allergic response; whereas, dextrose (corn sugar manufactured from cornstarch) can prove fatal to corn-allergic patients/consumers.  Therefore, the terms "blood sugar" (glucose) and "corn sugar" (dextrose) must never be used interchangeably for the safety of citizens with an IgE-mediated allergy to corn.
Since this page, as written, endangers the lives of anyone with an IgE-mediated allergy to corn; I am submitting an urgent appeal for the immediate removal or edit of this page.DextroseIsCornSugar (talk) 09:43, 12 September 2020 (UTC)

"Each glucose isomer is subject to rotational isomerism. Within the cyclic form of glucose, rotation may occur around the O6-C6-C5-O5 torsion angle, termed the ω-angle, to form three staggered rotamer conformations called gauche-gauche (gg), gauche-trans (gt) and trans-gauche (tg).For methyl α-D-glucuopyranose at equilibrium, the ratio of molecules in each rotamer conformation is reported to be  57% gg, 38% gt, and 5% tg. See . There is a tendency for the ω-angle to adopt a gauche conformation, a tendency that is attributed to the gauche effect."--Smokefoot (talk) 14:21, 10 May 2021 (UTC)
