what is sugar in biology
Glucose. Glucose (Glc), a monosaccharide (or simple sugar), is an important carbohydrate in biology. The living cell uses it as a source of energy and metabolic intermediate. Glucose is one of the main products of photosynthesis and starts cellular respiration in both prokaryotes and eukaryotes.glucose.-glucose is a short form of dextrorotatory glucose. It is one of the two stereoisomers of glucose, and is the one that is biologically active. It occurs in plant s as a product of photosynthesis. In animals and fungi, it is the result of the breakdown of glycogen.
Two monosaccharides joined together by a glycosidic linkage is called a double sugar or disaccharide. The most common disaccharide is sucrose. It is composed of glucose and fructose. Sucrose is commonly used by plants to transport sugar from one part of the plant to another.Disaccharides are also oligosaccharides.he most common disaccharide is sucrose.
