PARTOF_CpPG

The Compound is a component of the Pathway Group and plays an important role in the structure and function of the complex.
For example, GDP might be part of a PwGroup if RAS nucleotide exchange is involved in a Reaction that the PwGroup PARTICIPATES_PGpR in.

Other examples:
The Compound "27-Hydroxycholesterol" is PARTOF_CpPG the PwGroup "27-OH-CHOL:ESR1,2" which PARTICIPATES_PGpR in the Reaction "27-hydroxysterol binds ESR1, ESR2"
The Compound "2-Oxoglutaric acid" is PARTOF_CpPG the PwGroup "OXGR1:2OG " which PARTICIPATES_PGpR in the Reaction "OXGR1 binds 2OG"
