Glycogen: The Storage Polysaccharide in Muscles and Liver

The polysaccharide in muscles containing multiple glucose molecules is called glycogen. Glycogen is a branched polysaccharide composed of glucose units linked together by α-1,4-glycosidic bonds. It is the primary storage form of glucose in animals and humans, and is found in the liver and muscles. When the body needs energy, glycogen can be broken down to release glucose into the bloodstream.
