'''Glucagon''' is a chemical used in the body to stimulate secretion of [[glucose]] into the bloodstream. Glucagon itself is produced in the pancreas, where it is stored until [[hypoglycemia]] occurs. It has an effect opposite that of [[insulin]], which instead reduces the amount of glucose. Specifically, glucagon breaks down [[glycogen]] in the liver into glucose molecules that increase the blood sugar level. Glucagon also has a side effect of creating glucose from proteins, called gluconeogenesis.
