Hydrogen sulfide(H2S)is an important endogenous signalling molecule with multibiological functions.Studies have shown that H2S level is correlated with numerous diseases,including the symptoms of Alzheimers disease,Down syndrome,diabetes and liver cirrhosis[1].Now we knowed that endogenous H2S is induced by L-Cys and D-Cys including cystathionine β-synthase(CBS),cystathionine γ-lyase(CSE)and 3-mercaptopyruvate sulfurtransferase(3MPST)/cysteine aminotransferase(CAT)[2-3].
