Evidence (4)
Imported from CultureBotHT. CAS-RN 91510-62-2 present, but no CHEBI entry exists (checked OAK CHEBI sqlite + PubChem CID synonyms). FEBA/Hans80 panels: FEBA_carbon. Curator can promote to a CHEBI primary if/when CHEBI adds the term.
Parent class identified via stem-substring; matched_via='D-Galacturonic Acid monohydrate'
mapping_quality NARROW_MATCH -> CLOSE_MATCH, predicate skos:narrowMatch -> skos:closeMatch. narrowMatch asserts this record is *narrower in meaning* than CHEBI:18024 ('D-galacturonic acid') — a subsumption ChEBI itself denies: it files hydrates under CHEBI:35505 'hydrate', never under the anhydrous compound, which is not an ancestor even transitively. A hydrate is a distinct substance containing the anhydrous form, not a specialization of it. closeMatch claims similarity without subsumption. The ontology_id and the record's own identifier are unchanged.
molecular_formula 'C6H10O7' -> 'C6H10O7.H2O'. The recorded value described the anhydrous salt while the label names a hydrate, understating the mass by 18 g/mol per water. Corrected because the label states 1 water(s) of hydration, and the recorded formula was byte-identical to the anhydrous parent CHEBI:18024's ChEBI formula ('C6H10O7') — the mark of a value inherited from the parent rather than measured for this record. Water appended in ChEBI's own dot-separated notation.
