135_conjugate_acid_base_pair

ChEBI
Metabolite

Given a ChEBI compound, find the acid it is the conjugate base of (e.g. ammonia, CHEBI:16134, is the conjugate base of ammonium), using the direct chemrof:conjugate_base_of predicate rather than the OWL-restriction pattern used elsewhere in this project for the same underlying relationship.
