How are steroids metabolized

WebMany drugs are broken down (metabolized) with the help of a vital enzyme called CYP3A4 in the small intestine. Grapefruit juice can block the action of intestinal CYP3A4, so instead of being metabolized, more of the drug enters the blood and stays in the body longer. The result: too much drug in your body. WebSteroids with 21 carbon atoms are known systematically as pregnanes, whereas those containing 18 and 19 carbon atoms are known as estranges and androstanes, respectively. The important mammalian steroid hormones are shown in Table 50-1 along with the structure of the precursor, pregnenolone.
