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.
By Dr Ananya Mandal, MD. Insulin is a hormone that is important for metabolism and utilization of energy from the ingested nutrients - especially glucose. Insulin is a protein chain or peptide hormone. There are 51 amino acids in an insulin molecule. It has a molecular weight of 5808 Da. Insulin is produced in the islets of Langerhans in the pancreas. The name insulin comes from the Latin ''insula'' for island from the cells that produce the hormone in the pancreas.
