Glycogen is a polysaccharide molecule stored in animal cells along with water and used as a source of energy. When broken down in the body, it is transformed into glucose, an important source of energy for animals. In animals, it plays a role similar to that played by starch in plants.
Glycogen is a molecule made by the liver, muscles, brain, uterus (of pregnant women), and stomach which is the secondary energy storage in animal cells. It is often referred to as animal starch and plays an important part in the glucose cycle. It helps cells store glucose ensuring them of a steady supply of energy.
