The total amount of serum cholesterol is under close homeostatic control. It is influenced by dietary intake, production in the liver from fatty acids, and tissue utilization. It is also taken up by the liver and metabolized. The liver excretes cholesterol unchanged or as bile acids into the gastrointestinal tract.

terol cannot be metabolized to CO 2 and water in the body because human tissues do not possess enzymes that are able to degrade the ring structure of this sterol. Thus, to prevent a potentially hazardous accumulation of cho-lesterol in the human body, excess cholesterol has to be metabolized to other compounds and/or excreted in the feces.

Cholesterol is metabolized to a variety of important biological products in the body including bile acids and vitamin D. The present investigation is focused on enzymes that catalyze 7α-hydroxylation or 27-hydroxylation in the metabolism of cholesterol, oxysterols (side chain-hydroxylated derivatives of cholesterol) and vitamin D 3
