What is glycogen?

  • (noun): One form in which body fuel is stored; stored primarily in the liver and broken down into glucose when needed by the body.
    Synonyms: animal starch


Glycogen is a multibranched polysaccharide that serves as a form of energy storage in animals and fungi. In humans, glycogen is made and stored primarily in the cells of the liver and the muscles, and functions as the secondary long-term energy storage (with the primary energy stores being fats held in adipose tissue).
