Effect of taurine on mouse health
Taurine in mice is produced primarily through a two‑step enzymatic conversion of cysteine. The first reaction, catalyzed by cysteine dioxygenase (CDO), generates cysteine sulfinic acid. The second reaction, mediated by cysteine‑sulfinic acid decarboxylase (CSAD), yields hypotaurine, which is subsequently oxidized to taurine.. Date latest changes:
