胰岛素原由81个氨基酸残基构成，具有明显的结构分区，分别为B链、A链和C肽．其中，B链和A链的结构比较稳定，而C肽的结构比较松散．整个胰岛素原分子含有3对二硫键，其中2对二硫键(A6一B6，A20一B19)位于B链和A链之间，1对链内二硫键(A6～A11)位于A链内部．生物体中二硫键的氧化还原作用导致的生物化学反应与许多重要的生物学功能有关。本实验就是通过电化学研究胰岛素化学特性和二硫键的电化学活性

Answer 1

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

Answer 2
