all-cis-5,8,11,14,17-icosapentaenoic acid
CHEBI:28364 EXACT SEEDED enzyme inhibitor
What these status tags mean
Curation status describes a workflow state. SEEDED means the record entered through the source-seeding workflow; it does not imply that no later curation occurred. PROPOSED marks an addition awaiting review; REVIEWED records curator sign-off on identity, structure, filing class and producer claims; DEPRECATED retains a superseded or out-of-scope record. These are workflow decisions, not independently verified human review. Agent-assisted contributions may appear in the record history.
Grounding describes the identifier mapping: EXACT uses an ontology identity asserted by the source; MINTED keeps a local identifier when no defensible ontology identity is available; REVIEW_NEEDED flags an exact structure whose ontology identity needs adjudication. The grounding note retains any unresolved alternatives. These tags do not establish the strength of producer or activity evidence.
An icosapentaenoic acid having five cis-double bonds at positions 5, 8, 11, 14 and 17.

Fatty acids — computed by NPClassifier npclassifier.gnps2.org@2026-09-07, which is why it is pinned rather than recomputed. The gene cluster's asserted class is other, from MIBiG.
Producer organisms 4
A claim that this taxon makes the compound. The basis says what the evidence addressed — a knockout and a database assertion are not the same claim.

Open questions 2
name-disagreement — ChEBI calls this structure 'all-cis-5,8,11,14,17-icosapentaenoic acid' and MIBiG calls it 'eicosapentaenoic acid', 'eicoseicosapentaenoic acid'. They share a Standard InChIKey, so if the names denote different compounds then one upstream record has the wrong structure. Check which.
shared-structure — This structure is reported by more than one MIBiG entry: BGC0000861, BGC0000862, BGC0000863, BGC0000865. Confirm they describe the same compound rather than an upstream cross-reference error.
