Glycogen is a polysaccharide that is the principal storage form of glucose (Glc) in animal and human cells. Glycogen is found in the form of granules in the cytosol in many cell types. Hepatocytes (liver cells) have the highest concentration of it - up to 8% of the fresh weight in well fed state, or 100-120 g in an adult. In the muscles, glycogen is found in a much lower concentration (1% of the muscle mass), but the total amount exceeds that in liver. Small amounts of glycogen are found in the kidneys, and even smaller amounts in certain glial cells in the brain and white blood cells. Glycogen plays an important role in the glucose cycle.
, Developmental biologist. 1  Glycogen is used for storing energy, and is mostly stored in the muscles and liver, where it is both made (from the glucose in the blood that's produced by digesting food) and used, and red blood cells, where it is used. It is made up of lots of single glucose (a type of single sugar unit) molecules joined up together in a branched structure.
