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.
Human insulin is made of two amino acid chains, called A and B, that have two disulfide bonds between them. In glargine, one amino acid has been switched out, and two extra amino acids have been added to one end of the B chain. To make Lantus, first the glargine is produced by a vat of E. coli bacteria.
