This regulation occurs at the level of transcription of several genes encoding enzymes in the bile acid biosynthetic pathway. One of these enzymes is sterol 12alpha-hydroxylase/CYP8B1 (12alpha-hydroxylase), the specific enzyme required for cholic acid synthesis." . . "Selventa" . . . . "2014-07-03T14:29:58.336+02:00"^^ . . .
