How much glycogen can the liver store?

The liver can store approximately 100-120 grams of glycogen. Glycogen is a complex polysaccharide that serves as a primary energy reserve for the body, particularly in the liver and skeletal muscles. When glucose levels in the bloodstream are high, such as after a meal, the liver converts the excess glucose into glycogen through a process called glycogenesis. This stored glycogen can then be broken down into glucose and released into the bloodstream when the body requires energy, such as during exercise or fasting. The liver's glycogen stores provide a readily available source of glucose to maintain normal blood sugar levels and fuel various bodily functions.
