General description
7α-Hydroxy-4-cholesten-3-one (C4) is known as a marker for the cholesterol 7α-hydroxylase activity. It plays an important role in bile acid metabolism.
Application
C4 may be used as a reference standard for the determination of C4 in:
- Human serum by ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) with electrospray ionization source (ESI) as well as LC-MS.
- Rat and monkey plasma by LC-ESI-MS/MS working on multiple reaction monitoring (MRM) mode of detection.
- Peripheral blood plasma by solid-phase extraction (SPE) and HPLC.
Biochem/physiol Actions
7a-Hydroxycholestene-3-one, a metabolite in bile acid synthesis, is derived from 7a-hydroxycholesterol and can be further metabolized to 7a,12a,-dihydroxycholest-4-en-3-one. Analysis of 7a-Hydroxycholestene-3-one (HCO) in serum may serve as a novel, simple, and sensitive method for the detection of bile acid malabsorption in patients with chronic diarrhea of unknown origin.

7α-hydroxy-4-cholesten-3-one (C4) is an oxidative enzymatic product of cholesterol metabolism via cholesterol 7α-hydroxylase, an enzyme also known as cholesterol 7-alpha-monooxygenase or cytochrome P450 7A1 (CYP7A1). C4 is a stable intermediate in the rate limiting pathway of bile acid biosynthesis. Previous
