Explain Glycogen
Glycogen is the storage polysaccharide found in the muscle and liver of animals and humans. It is a branched polymer having about 8 to 10 glucose units in each branch. Like amylopectin, its straight chains are formed by a(1,4) glycosidic linkages and a(1,6) glycosidic linkage exists at branch points. Thus, the chemical structure of glycogen and amylopectin are similar except that the former is more branched.
