Abstract

The reactivity of dL-cysteine, a physiologically important aminothiol, was studied by reacting it with several well known oxidants. No activity was observed on the amino and carboxyl groups. The only reactivity of physiological significance was at the sulfur centre. Reactions of cysteine with hydrogen peroxide show
