WebThis is because the disulfide bonds (established during the initial folding of the protein, during its synthesis), reduce the number of possible ways to "misfold". Quaternary Structure In nature, some proteins are formed from multiple proteins, also known as subunits, and the interaction of these subunits forms the quaternary structure . 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.
