Imported from CultureMech pipeline, quality=DIRECT_MATCH
MANUAL_CURATION
via cbclaw_kg_microbe_sweep
Corrected from CHEBI:150970 (a complex polysaccharide — unrelated compound) to CHEBI:25351 (mevalonic acid, the racemic parent). CAS-RN 150-97-0 confirms mevalonic acid.

The record's label does not equal the term's primary label 'mevalonic acid'; preferred_term 'DL-mevalonic acid' matches the ChEBI synonym 'DL-mevalonic acid' on CHEBI:25351. The schema defines EXACT_MATCH as a direct match to the term and SYNONYM_MATCH as a match to a known synonym, so the recorded grade overstated. ontology_id is unchanged — the term is correct. The own-identifier SSSOM predicate remains skos:exactMatch under Rule D (#438), independently of mapping quality. | |

ChEBI gives these names to CHEBI:150970, not to this record's CHEBI:25351 -- mevalonic acid is not the oligosaccharide at CHEBI:150970 -- its CAS 150-97-0 read as an accession. Kept as REJECTED_LABEL so a rebuild cannot restore them from kg-microbe's synonym list (#669). |
