| Common Name | (24R)-Cholest-5-ene-3-beta,24-diol |
|---|
| Description | (24R)-Cholest-5-ene-3-beta,24-diol or 24(R)-Hydroxycholesterol is a hydroxysterol. It is a substrate for Cytochrome P450 39A1 (EC 1.14.13.99), which is primarily a liver-specific enzyme. It is involved in the following reaction: (24R)-cholest-5-ene-3-beta,24-diol + NADPH + O(2) = (24R)-cholest-5-ene-3-beta,7-alpha,24-triol + NADP(+) + H(2)O. 24(R)-Hydroxycholesterol is an intermediate in bile acid metabolism. The majority of circulating 24-hydroxycholesterol in humans is made in the brain and is increased in serum of Alzheimer patients. 24(S)-Hydroxycholesterol is generally more abundant in human tissues than 24(R)-Hydroxycholesterol. It has also been shown that 24(R) and 24(S)-Hydroxycholesterols are substrates for hepatic cholesterol 7-a hydroxylase (CYP7A), leading to the production of 7-alpha hydroxylated bile acids. |
