Common Name(24R)-Cholest-5-ene-3-beta,7-alpha,24-triol
Description(24R)-Cholest-5-ene-3-beta,7-alpha,24-triol is a hydroxysterol and a bile acid intermediate. It is produced from the reaction of 24(R)-Hydroxycholesterol with the enzyme CYP39A, which is also known as 24-hydroxycholesterol 7alpha-hydroxylase (EC 1.14.13.99). This enzyme catalyzes the following reaction: (24R)-cholest-5-ene-3beta,24-diol + NADPH + H+ O2 = (24R)-cholest-5-ene-3beta,7alpha,24-triol + NADP+ + H2O. This leads to the 7-alpha hydroxylation of 24(R)-hydroxycholesterol. This enzyme can act on both the 24R and 24S isomers.
