WebAbstract. Disulfide bonds can be cleaved at an alkaline p H by treating a protein with excess of a reagent disulfide in the presence of catalytic amounts of thiol. The cleavage products are stable and can be isolated; they contain the mixed disulfide between the reagent and the exposed thiol groups of the protein. 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.
