BIOMOLECULES AND ENZYMES

Detailed explanation-1: -It is a branched polysaccharide composed of alpha-D-glucose units with -1, 4 and -1, 6-glycosidic bonds. It is more highly branched than amylopectin. Cellulose is a structural polysaccharide of glucose units found in plants.

Detailed explanation-2: -The glucose units in cellulose are linked by glycosidic bonds, different than the glycosidic bonds found in glycogen and starch. Cellulose has more hydrogen bonds between adjacent glucose units, both within a chain and between adjacent chains, making it a tougher fiber than glycogen or starch.

Detailed explanation-3: -Like amylose, cellulose is a linear polymer of glucose. It differs, however, in that the glucose units are joined by -1, 4-glycosidic linkages, producing a more extended structure than amylose (part (a) of Figure 5.1. 3).

Detailed explanation-4: -Cellulose is a polysaccharide composed of a linear chain of -1, 4 linked d-glucose units with a degree of polymerization ranged from several hundreds to over ten thousands, which is the most abundant organic polymer on the earth.
