How are disulfide bonds formed

WebDisulfide bond plays a very much important role to form the secondary structure of protein. It is basically a covalent type bond. Disulfide bond is formed by the oxidation of sulfyhydryl or thiol group (S-H group), present only in Cysteine amino acid (non essential amino acid). It is also known as S-S bond . Disulfide bond is denoted by R-S-S-R1. Web7 de mar. de 2024 · Disulfide bonds, formed by two sulfur molecules, are common bonds made to achieve this effect.
