MANUAL_CURATION via MIM curation (#312); chebi.db

identifier CHEBI:28793 -> kgmicrobe.ingredient:b-glucan_from_oat; ontology CHEBI:28793 ('beta-D-glucan') -> CHEBI:18504 ('(1->3,1->4)-beta-D-glucan'); mapping_quality CAS_RN_LOOKUP -> NARROW_MATCH. CHEBI:28793 'beta-D-glucan' is the linkage-agnostic class with 18 subclasses (cellulose, nitrocellulose, schizophyllan, ...); an exactMatch licensed substituting oat beta-glucan for the whole class, and MIM:Cellulose already sits under it. Oat beta-glucan is the mixed-linkage (1->3,1->4)-beta-D-glucan, CHEBI:18504, and the record is source-qualified ('from Oat'), so it is narrower than that term too. Section 3 step 3, the Amylopectin_From_Maize / Lichenan shape: registry identity, broadMatch CHEBI:18504. CAS 9041-22-9 is the generic beta-glucan registration (ChEBI xrefs it on CHEBI:28793) and stays in chemical_properties as such.

The record was created by an explicit CAS-to-ChEBI lookup and its current CAS RN 9041-22-9 uniquely resolves by ChEBI xref to CHEBI:28793 'beta-D-glucan'. CAS_RN_LOOKUP records the method that established this mapping; a lexical grade would discard that provenance. ontology_id is unchanged. The own-identifier SSSOM predicate remains skos:exactMatch under Rule D (#438), independently of mapping quality.
