Insulin originally 81 amino acid residues with obvious structural partitions, respectively, B chain, A chain and C peptide. Where, B chain and A chain structure is relatively stable, while the loose structure of C peptide. The insulin molecule contains three pairs of disulfide bonds, of which two pairs of disulfide bond (A6 a B6, A20 a B19) is located between the B chain and A chain, 1 on the chain disulfide bond (A6 ~ A11) in the A-chain inside. Organisms in the role of the redox disulfide caused many important biochemical reactions and biological functions. This experiment is through electrochemical and chemical properties of insulin disulfide electrochemical activity
