The poly saccharide stored by vertebrates in liver and skeletal muscles is

This is the main storage poly-saccharide in animals. Vertebrate animals store glycogen in liver and skeletal muscles. Stored glycogen may respectively account for upto 10% and 2% of liver and muscles by weight in man and other animals. Thus, a total of about 400 grams of glycogen (about 100 gm in liver and about 300 gm in skeletal muscles) is normally found in the body of an average adult human being. In liver cells, the glycogen is found in large, flattened and ellipsoidal grains.
