Glycogen, also termed as animal starch, is a branched polysaccharide that behaves as an energy reserve in the liver and muscle. It is readily available as an immediate source of energy. The formation of glycogen from glucose is otherwise known as glycogenesis, and the breakdown of glycogen to form glucose is also termed as glycogen metabolism or glycogenolysis. Glycogenolysis is the breakdown of glycogen caused by increased cyclic adenosine monophosphate (cAMP).
