This value set expansion contains 2 concepts.

System	Version	Code	Display	Definition
`http://terminology.hl7.org/CodeSystem/v3-RoleClass`	3.1.0	BOND	molecular bond	A connection between two atoms of a molecule. Examples: double bond between first and second C in ethane, peptide bond between two amino-acid, disulfide bridge between two proteins, chelate and ion associations, even the much weaker van-der-Waals bonds can be considered molecular bonds. UsageConstraints: See connection and adjacency for the assignment of player and scoper.
`http://terminology.hl7.org/CodeSystem/v3-RoleClass`	3.1.0	PART	part	Definition: an association between two Entities where the playing Entity (the part) is a component of the whole (scoper) in the sense of an integral structural component, that is distinct from other parts in the same whole, has a distinct function in the whole, and, as an effect, the full integrity of the whole depends (to some degree) on the presence of this part, even though the part may often be separable from the whole. Discussion: Part is defined in opposition to (a) ingredient (not separable), (b) content (not a functional component), and (c) member (not functionally distinct from other members).
