What is glycogen ? How is it different form starch?
QUESTION 14.6
Glycogen is a plysaccharide (carbohydrate) which is stored in the animal body. It is present in the liver, muscles, and brain. When the body needs glucose, enzymes break down the glycogen into glucose,
Starch is a polysaccharide which is stored in plants. It consists of two components amylose and amylopectin. Amylose is water soluble and makes 15-20 % of starch. Amylopectin is insoluble in water and makes 80-85% of starch
Glycogen mainly resembles amylopectin in structure. Both glycogen and amylopectin are branched polymers of glucose but glycogen is highly branchedd than amylopectin. Glycogen chain consists of 10-14 glucose units whereas amylopectin chains consist of 20-25glucosee units.
