In a human body at rest, approximately 100 to 120 grams of glycogen can be stored within the liver, comprising up to 8% of its fresh weight. This remarkable biological feat is made possible by glycogen, the polysaccharide synthesized and stored in liver cells to regulate blood glucose levels.

Approximately 70-85% of the liver's volume is composed of specialized cells called hepatocytes, which are responsible for most of its metabolic functions. Understanding this cellular structure is key to answering whether the liver is made up of protein and clarifying its complex biological role.

An estimated 400 grams of glycogen is stored in the skeletal muscle of an average adult, accounting for the largest share of the body's total stores. This molecule, known as glycogen, is what is used to store sugar in liver and muscle cells of animals, acting as a crucial short-term energy reserve.
