Compare the different types of the polysaccharides – glycogen, starch, and cellulose. What is the function? How is the structure of the polysaccharide forms?
Glycogen, starch, and cellulose are polysaccharides. They all are homopolysaccharide. They all have different glycosidic linkages. cellulose is formed by the monomer of beta glucose and it is mainly constitute the plant cell wall. Starch is a carbohydrate reserve in plants and Glycogen act as the carbohydrate reserve in animals and it is also found in plants as well. The Cellulose structure is formed by glucose residues as ?(1-4) glycosidic bonds. Glucose residues as ?(1-4) glycosidic bonds in amylose, and in amylopectin ?(1-6) glycosidic linkages at branching points, constitute the starch structure. Glycogen is formed by ?(1-4) and ?(1-6) glycosidic bonds. Cellulose is insoluble in water and it forms fibres. Starch have Amylose is soluble in water, and amylopectin is insoluble in water. It forms grain. Glycogen is soluble in water up to some extent. It forms Small granules.
