selenomethionine.Although the structure of selenomethionine and methionine are similar,the electron supply ability of selenomethionine is lower than that of methionine.Conclusion Methionine as electrons provider could accelerate the photolysis of VB2 to generate ?O 2,but selenocystine,selenomethionine and cystine could directily scavenge ?O 2 generated by VB2.
