Insulin is a peptide hormone produced by beta cells in the pancreas. It regulates the metabolism of carbohydrates and fats; in addition, it stores fat to be used for energy later. When you eat, your blood sugar increases, which causes insulin to be released.
Glucose-dependent insulinotropic peptide is a hormone released from the small intestine that enhances the release of insulin following the intake of food. It is a member of the family of hormones known as the incretins of which the other main member is the hormone glucagon-like peptide 1. Glucose-dependent insulinotropic peptide is made and secreted mainly from the upper section of the small intestine from a specific type of cell known as the K cell. Its main action occurs in the pancreas where it targets beta cells which produce insulin. Glucose-dependent insulinotropic peptide stimulates the release of insulin from the beta cells in the pancreas in order to maintain low blood sugar levels after eating.
