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.
One rapid-acting insulin analog is insulin lispro, which is marketed by Eli Lilly and Company as Humalog and became commercially available in 1996. The structure of the insulin lispro molecule is identical to that of human insulin except that the amino acids at two positions on the B chain, B28 and B29, are reversed.nsulin is a hormone, or chemical messenger that is released into the bloodstream to be transported throughout the body. Most hormones, including insulin, are proteins, which means that they are made up of molecules called amino acids.
