Fig. 2From: The metabolism and significance of homocysteine in nutrition and healthFormation of Hydrogen Sulfide in vivo. The in vivo formation of Hydrogen sulfide is presented. This can be formed from the disulfide of cysteine-Cystine (Cys-Cys) or the mixed disulfide of cysteine and homocysteine (Cys-Hcy). α-KB- α-ketobutyrate, CβS- Cystathionine β synthase, CSE- Cystathionine γ lyase, H2S- Hydrogen sulfideBack to article page
