why is glycogen used in exercise
Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals and fungi. The polysaccharide structure represents the main storage form of glucose in the body.hen it is needed for energy, glycogen is broken down and converted again to glucose. Glycogen phosphorylase is the primary enzyme of glycogen breakdown. For the next 8â12 hours, glucose derived from liver glycogen is the primary source of blood glucose used by the rest of the body for fuel.
