WebDisulfide Bond Function. Function of disulfide bond in the determining the structure of protein is widespread. The main activity of disulfide bond is to provide stabilization to the 3D structure of protein and exhibit physiologically appropriate redox procedure. Disulfide bond is an essential part in protein folding and stability. WebCysteine is the sole amino acid whose side chain can form covalent bonds, yielding disulfide bridges with other cysteine side chains: --CH 2 - S - S -CH 2 --. Here, cysteine 201 of the model peptide is seen to be covalently bonded with cysteine 136 from an adjacent β-strand. Return to Beginning III. Electrostatic Interactions
