Biochem/physiol Actions

Human insulin is made up of 51 amino acids. It consists of two peptide chains, 21 amino acids make up A-chain and chain B contains 31 amino acids. The two chains are linked together by a disulfide bond, to form a classical insulin fold with three α helices, chain A having two and one in chain B.

Insulin regulates the cellular uptake, utilization, and storage of glucose, amino acids, and fatty acids. It inhibits the breakdown of glycogen, protein, and fat. The α chain contains an intrachain disulfide bond.
