Metabolite Identification
Common Name7alpha,12alpha-Dihydroxycholest-4-en-3-one
Description7alpha,12alpha-Dihydroxycholest-4-en-3-one belongs to the class of organic compounds known as cholesterols and derivatives. Cholesterols and derivatives are compounds containing a 3-hydroxylated cholestane core. Based on a literature review very few articles have been published on 7alpha,12alpha-Dihydroxycholest-4-en-3-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). 7alpha,12alpha-dihydroxycholest-4-en-3-one is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 7alpha,12alpha-Dihydroxycholest-4-en-3-one is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
Efficiently catalyzes the reduction of progesterone, androstenedione, 17-alpha-hydroxyprogesterone and testosterone to 5-beta-reduced metabolites. The bile acid intermediates 7-alpha,12-alpha-dihydroxy-4-cholesten-3-one and 7-alpha-hydroxy-4-cholesten-3-one can also act as substrates.
Gene Name:
AKR1D1
Uniprot ID:
P51857
Molecular weight:
32889.38
General function:
Involved in monooxygenase activity
Specific function:
Involved in bile acid synthesis and is responsible for the conversion of 7 alpha-hydroxy-4-cholesten-3-one into 7 alpha, 12 alpha-dihydroxy-4-cholesten-3-one. Responsible for the balance between formation of cholic acid and chenodeoxycholic acid. Has a rather broad substrate specificity including a number of 7-alpha-hydroxylated C27 steroids.
Gene Name:
CYP8B1
Uniprot ID:
Q9UNU6
Molecular weight:
58068.01
General function:
Not Available
Specific function:
A cytochrome P450 monooxygenase involved in primary bile acid biosynthesis. Catalyzes the 12alpha-hydroxylation of 7alpha-hydroxy-4-cholesten-3-one, an intermediate metabolite in cholic acid biosynthesis (By similarity). Controls biliary balance of cholic acid and chenodeoxycholic acid, ultimately regulating the intestinal absorption of dietary lipids (PubMed:12393855, PubMed:28377401). Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (CPR; NADPH--hemoprotein reductase) (By similarity).
