Detailed explanation-1: -Glycogen is a multi-branched polymer of glucose that is used to store energy in animals. The polysaccharide structure is the body’s primary glucose storage structure. In both animals and humans, it is predominantly found in muscle and liver cells.
Detailed explanation-2: -Glycogen is a glucose polysaccharide occurring in most mammalian and nonmammalian cells, in microorganisms, and even in some plants. It is an important and quickly mobilized source of stored glucose. In vertebrates it is stored mainly in the liver as a reserve of glucose for other tissues.
Detailed explanation-3: -Plants store carbohydrates in long polysaccharides chains called starch, while animals store carbohydrates as the molecule glycogen. These large polysaccharides contain many chemical bonds and therefore store a lot of chemical energy.
