WebFeb 12, 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. Notice that in the oxidized (disulfide) state, each sulfur atom has lost a bond to ...
