In humans, glycogen is stored and produced by the hepatocytes in the liver. The main function of glycogen is as a secondary long-term energy-storage molecule. The primary energy-storage molecules are adipose cells. Glycogen is also stored in muscle cells. Muscle glycogen is converted into glucose by the muscle cells whenever muscles are overworked and tired.
Glycogen is considered the principal storage form of glucose and is found mainly in liver and muscle, with kidney and intestines adding minor storage sites. With up to 10% of its weight as glycogen, the liver has the highest specific content of any body tissue. Muscle has a much lower amount of glycogen per unit mass of tissue, but since the total mass of muscle is so much greater than that of liver, total glycogen stored in muscle is about twice that of liver.
