WebDisulfide bonds are covalent interactions formed between the sulfur atoms of two cysteine residues. As structural bonds in proteins, disulfide bonds stabilize monomeric and multisubunit proteins [1] constituting the only natural covalent link between polypeptide strands. Furthermore, disulfide bonds are involved in enzyme catalysis [2], regulate … 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.
