Glucose Metabolism Impact Factor

 The normal functioning of the organs in the body needs energy. Many tissues can also use fat or protein as a source of energy, while others can only use glucose, such as the brain and red blood cells. Glucose is stored as glycogen in the body. The liver represents an essential glycogen storage site. Once the concentration of blood glucose is low, Glycogen is activated and converted to glucose by gluconeogenesis. Glucose can also be formed by gluconeogenesis from non-carbohydrate precursors, such as pyruvate, amino acids and glycerol. Gluconeogenesis is the one that regulates concentrations of blood glucose during hunger and vigorous exercise for example.
