Insulin is a peptide hormone produced by beta cells of the pancreatic islets. It regulates the metabolism of carbohydrates, especially the absorption of glucose from the blood into the liver, fat and skeletal muscle cells. Impaired insulin production or insulin resistance lead to various forms of diabetes mellitus diseases. Insulin is used to treat patients with severe forms of type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM).
