Data Sheet Material Safety Data Sheet (MSDS)

Insulin is a polypeptide composed of two peptide chains referred to as the α chain and β chain. These chains are linked by two disulphide bonds, and an additional disulphide is formed within the α chain. In most species, the α chain consists of 21 amino acids and the β chain of 30 amino acids. Insulin is normally secreted rapidly from the beta-cells of the pancreatic islets in response to nutrients absorbed after a meal. In type 1 diabetes mellitus, there may be an absolute insulin deficiency as a consequence of autoimmune destruction of the beta-cells. On the other hand, in type 2 diabetes mellitus, insulin secretion is impaired and is inadequate to overcome peripheral insulin resistance.
