A 57 -year-old man has been admitted with congestive heart failure. He has been given Digoxin, which helps the heart to beat more strongly and regularly. Digoxin is an ester that contains a sugar component (glycol) and a nonsugar (aglycone) component attached via oxygen. Digoxin should be best classified as a: A. Disaccharide B. Glycoprotein […]

Q.1- What are storage polysaccharides? Give a brief description of each of them. Answer- Glycogen, starch, and Inulin are storage polysaccharides. 1) Glycogen- Glycogen is a readily mobilized storage form of glucose. It is a very large, branched polymer of glucose residues (Figure-1) that can be broken down to yield glucose molecules when energy is needed.

Q.1- Give a brief account of the disaccharides of biological importance. Answer- The disaccharides are sugars composed of two monosaccharide residues linked by a glycoside bond. The glycosidic bonds are readily hydrolyzed by acids but resist cleavage by alkaline hydrolysis. The glycosidic linkage is formed by loss of one molecule of water as shown in the
