chemical entity
METPO:1000526 · CLASS · REVIEWED
A material entity that is a physical entity of interest in chemistry, including molecular entities, parts thereof, and chemical substances. Used as the range class for the majority of METPO chemical-use OBJECT_PROPERTYs (uses_as_carbon_source, uses_as_electron_donor, ferments, oxidizes, etc.) so that organism-to-chemical assertions resolve to a curated chemical class.

CREATED_UPPER_CLASS_RECORD · claude
Created upper-ontology CLASS record for METPO:1000526 (chemical entity) so that the range of un-deprecated metabolism OBJECT_PROPERTYs resolves to a curated TraitMech record. Added xref to CHEBI:24431, which is the exact ChEBI equivalent (same definition, same root position). TraitMech records can use either METPO:1000526 or CHEBI:24431 as range_; this xref makes them interconvertible.
