Metabolite Identification
Common Name7alpha-Hydroxy-3-oxo-4-cholestenoate
Description7alpha-Hydroxy-3-oxo-4-cholestenoate, also known as 7-Hoca, is a member of the class of compounds known as monohydroxy bile acids, alcohols, and derivatives. Thes compounds are bile acids, alcohols, or any of their derivatives bearing a hydroxyl group. 7alpha-Hydroxy-3-oxo-4-cholestenoate is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 7alpha-Hydroxy-3-oxo-4-cholestenoate is involved in metabolic disorders such as 27-hydroxylase deficiency, familial hypercholanemia (FHCA), and Zellweger syndrome. 7alpha-Hydroxy-3-oxo-4-cholestenoate is involved in the primary bile acid biosynthesis pathway. 7alpha-Hydroxy-3-oxo-4-cholestenoate is created from either 3beta,7alpha-dihydroxy-5-cholestenoate or 7alpha,26-dihydroxy-4-cholesten-3-one through the actions of HSD3B7 (EC 1.1.1.181) or CYP27A (EC 1.14.13.15), respectively.

Enzymes

General function:
Involved in monooxygenase activity
Specific function:
Catalyzes the first step in the oxidation of the side chain of sterol intermediates; the 27-hydroxylation of 5-beta-cholestane-3-alpha,7-alpha,12-alpha-triol. Has also a vitamin D3-25-hydroxylase activity.
Gene Name:
CYP27A1
Uniprot ID:
Q02318
Molecular weight:
60234.28
Reactions
7 alpha,26-Dihydroxy-4-cholesten-3-one + Oxygen + NADPH + Hydrogen Ion → 7alpha-Hydroxy-3-oxo-4-cholestenoate + NADP + Waterdetails
General function:
Involved in 3-beta-hydroxy-delta5-steroid dehydrogenase activity
Specific function:
The 3-beta-HSD enzymatic system plays a crucial role in the biosynthesis of all classes of hormonal steroids. HSD VII is active against four 7-alpha-hydroxylated sterols. Does not metabolize several different C(19/21) steroids as substrates. Involved in bile acid synthesis.
