Abstract
The riboflavin sensitized oxidation of cysteine under an aerobic condi tion was investigated, The effects of various scavengers, such as supe roxide dismutase, catalase, mannitol, sodium azide and potassium ferro cyanide (an electron donor), on the photooxidation were determined, A reaction mechanism involving the superoxide anion is proposed for the photooxidation of cysteine to cysteic acid.
