WebJul 20, 2024 · A disulfide bond is a sulfur-sulfur bond, usually formed from two free thiol groups. The interconversion between dithiol and disulfide groups is a redox reaction: the free dithiol form is in the reduced state, and the disulfide form is in the oxidized state. 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.
