Detailed explanation-1: -Cellulose is a structural polysaccharide formed of long chain of -glucose units (6000-10000).
Detailed explanation-2: -Structure of Starch and Cellulose Starch and cellulose are both homopolymers of glucose, meaning they are only made of repeating units of glucose molecules.
Detailed explanation-3: -Cellulose is formed by 1, 4 glycosidic bonds between hundreds of D-beta-glucose molecules and hydrogen bonds between the layers of the polysaccharide. This creates a highly organised crystalline structure, which plants use to maintain cell wall structure. Cellulose can be hydrolysed with enzymes back to glucose.
Detailed explanation-4: -Cellulose is a polysaccharide composed of a large number of -D-glucose units.
