where is glycogen stored in the human body
Glycogen
Glycogen functions as one of two forms of long - term energy reserves , with the other form being triglyceride stores in adipose tissue ( i.e. , body fat ) . In humans , glycogen is made and stored primarily in the cells of the liver and skeletal muscle . In the liver , glycogen can make up from 5 -- 6 % of the organ 's fresh weight and the liver of an adult weighing 70 kg can store roughly 100 -- 120 grams of glycogen . In skeletal muscle , glycogen is found in a low concentration ( 1 -- 2 % of the muscle mass ) and the skeletal muscle of an adult weighing 70 kg can store roughly 400 grams of glycogen . The amount of glycogen stored in the body -- particularly within the muscles and liver -- mostly depends on physical training , basal metabolic rate , and eating habits . Small amounts of glycogen are also found in other tissues and cells , including the kidneys , red blood cells , white blood cells , and glial cells in the brain . The uterus also stores glycogen during pregnancy to nourish the embryo .
