WebThis chapter focuses specifically on cytochrome P450 (CYP) enzymes, one of the most important drug metabolizing enzymes (DMEs), which are responsible for converting … WebSteroid hormones are synthesized through a series of chemical reactions. The CYP17A1 enzyme performs two important reactions in this process. The enzyme has 17 alpha (α)-hydroxylase activity, converting pregnenalone to 17-hydroxypregnenolone and progesterone to 17-hydroxyprogesterone.
