MANUAL_CURATION
via MIM curation (#260)
Added 'L-glutathione reduced' as a EXACT_SYNONYM (#260): CHEBI:16856 'glutathione' IS the reduced form (GSH) — the record already lists `Reduced glutathione` and `GSH`, and the oxidised form is a separate record on CHEBI:17858. The `L-` and `reduced` qualifiers add nothing the term does not already fix. CultureMech uses this surface form and label_index did not contain it, so the lookup missed. No new record: CHEBI:16856 is this record's identifier, and in MIM the identifier IS the ontology CURIE, so a second record on it would be a duplicate primary key rather than added coverage.
