Human insulin monomeric form,computer generated model based upon the Protein Data Bank coordinates for entry 2HIU. Circulating,and biologically active,insulin is monomeric. It is composed of two polypeptide chains: chain A (blue) has 21 amino acids and chain B (red) has 30 amino acids (in humans). Two disulfide bridges (residues A7 to B7,and A20 to B19) covalently tether the chains,and chain A contains an internal disulfide bridge (residues A6 to A11). Superimposed upon the 2 chains are the individual amino acids (shown as ball and stick models) that make up the chains | |
