Source-derived summary

In enzymology, a retinyl-palmitate esterase (EC 3.1.1.21) is an enzyme that catalyzes the chemical reaction.

retinyl palmitate + H2O

⇌

{\displaystyle \rightleftharpoons }

retinol + palmitate

Thus, the two substrates of this enzyme are retinyl palmitate and H2O, whereas its two products are retinol and palmitate.

This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name of this enzyme class is retinyl-palmitate palmitohydrolase. Other names in common use include retinyl palmitate hydrolase, retinyl palmitate hydrolyase, and retinyl ester hydrolase. This enzyme participates in retinol metabolism.

Editorial analysis

Why this record matters

“Retinyl-palmitate esterase” is worth following because a concise public description often conceals a longer documentary argument. Here, Retinyl-palmitate, esterase and obsolete provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 6, 2025. The linked authority identifier is Q9115759. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1966.

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
