In enzymology, a 24-hydroxycholesterol 7alpha-hydroxylase (EC 1.14.14.26) is an enzyme that catalyzes the chemical reaction

The four substrates of this enzyme are 24S-hydroxycholesterol, reduced nicotinamide adenine dinucleotide phosphate (NADPH), oxygen, and a proton. Its products are (24S)-7α,24-dihydroxycholesterol, oxidised NADP+, and water.

This enzyme is a cytochrome P450-type oxidoreductase, acting on paired donors, with molecular oxygen as oxidant and incorporating one of its atoms. The systematic name of this enzyme class is (24R)-cholest-5-ene-3beta,24-diol,NADPH:oxygen oxidoreductase (7alpha-hydroxylating). Other names in common use include 24-hydroxycholesterol 7alpha-monooxygenase, CYP39A1, and CYP39A1 oxysterol 7alpha-hydroxylase.

Editorial summary

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current 87-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around 24-hydroxycholesterol, 7alpha-hydroxylase and class.
Editorial analysis

Why this record matters

“24-hydroxycholesterol 7alpha-hydroxylase” is worth following because a concise public description often conceals a longer documentary argument. Here, 24-hydroxycholesterol, 7alpha-hydroxylase and class provides the most credible route into that argument.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Mar 28, 2026. The linked authority identifier is Q3598218. None of the 0 selected statements returned an explicit reference.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
