Background: Hydrogen sulfide (H2S) modulates physiological processes in mammals. Results: The reactivity of H2S toward disulfides (RSSR) and albumin sulfenic acid (RSOH) to form persulfides (RSSH) was assessed. Conclusion: H2S is less reactive than thiols. Persulfides have enhanced nucleophilicity. Significance: This kinetic study helps rationalize the contribution of the reactions with oxidized thiol derivatives to H2S biology.
