Source-derived summary

In enzymology, D-pinitol dehydrogenase (EC 1.1.1.142) is an enzyme that catalyzes the chemical reaction

The two substrates of this enzyme are pinitol and oxidised nicotinamide adenine dinucleotide phosphate (NADP+). Its products are 2D-5-O-methyl-2,3,5/4,6-pentahydroxycyclohexanone, reduced NADPH, and a proton.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 1D-3-O-methyl-chiro-inositol:NADP+ oxidoreductase. This enzyme is also called 5D-5-O-methyl-chiro-inositol:NADP+ oxidoreductase.

Editorial summary

The public source identifies “D-pinitol dehydrogenase” as class of enzymes. This brief keeps that definition visible, then builds a research path around D-pinitol, dehydrogenase and class.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current 78-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 value is orientation rather than verdict, with D-pinitol, dehydrogenase and class providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “D-pinitol dehydrogenase”, the useful work is to connect “class of enzymes” to the records capable of establishing context and consequence.

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 Dec 7, 2025. The linked authority identifier is Q2601874. None of the 0 selected statements returned an explicit reference.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
