Delta11-fatty-acid desaturase
class of enzymes
Delta11-fatty-acid desaturase (EC 1.14.19.5, Delta11 desaturase, fatty acid Delta11-desaturase, TpDESN, Cro-PG, Delta11 fatty acid desaturase, Z/E11-desaturase, Delta11-palmitoyl-CoA desaturase) is an enzyme with systematic name acyl-CoA,hydrogen donor:oxygen Delta11-oxidoreductase. This enzyme catalyses the following chemical reaction
acyl-CoA + reduced acceptor + O2
⇌
{\displaystyle \rightleftharpoons }
Delta11-acyl-CoA + acceptor + 2 H2O
The enzyme from the marine microalga Thalassiosira pseudonana desaturates palmitic acid 16:0 to 16:1Delta11, whereas that from the leafroller moth Choristoneura rosaceana desaturates myristic acid 14:0 to 14:1Delta11.
The public source identifies “Delta11-fatty-acid desaturase” as class of enzymes. This brief keeps that definition visible, then builds a research path around Delta11-fatty-acid, desaturase and class.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Delta11-fatty-acid desaturase”, the useful work is to connect “class of enzymes” to the records capable of establishing context and consequence.
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 Jul 30, 2025. The linked authority identifier is Q4122182. None of the 0 selected statements returned an explicit reference.
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
