http://purl.obolibrary.org/obo/RO_0020337	has_constituent_monomer	http://purl.obolibrary.org/obo/RO_0002180	has_component		A relation that holds between a polymer and its constituent monomers. P has_constituent_monomer c if and only if P has_component multiple instances of c and each instance of c is covalently attached to another instance of c.
http://purl.obolibrary.org/obo/RO_0020339	non-covalently_bound_to	http://purl.obolibrary.org/obo/RO_0002436	molecularly_interacts_with		A relation that holds between two distinct chemical entities that are held in close proximity to each other specifically via the force of non-covalent interactions. Such entities will colocalize at all times of the interaction.
