In the chebi.obo, there are entries (e.g., CHEBI:16761 ADP) that have:
synonym: "XTWYTFMLZFPYCI-KQYNXXCUSA-N" RELATED InChIKey [ChEBI:]
and other records (e.g., CHEBI:87728) that have:
synonym: "InChIKey=SMEROWZSTRWXGI-WFVDQZAMSA-M" RELATED InChIKey [ChEBI:]
When converting these data to BioPAX we use a pattern to capture InChIKey, and skip for entries that do not have the key. So ones without "InChIKey=" prefix do not make it into the PC2 warehouse BioPAX model.
