Macrocyclic component

{
  "id": "MLC-T-CHM-006864",
  "term": "Macrocyclic component",
  "field": "Chemistry",
  "definition": "A molecule containing at least one ring large enough to be threaded onto a linear section of another molecule, as in a rotaxane or pseudorotaxane. It is usually a discrete macrocyclic compound such as a crown ether, cyclodextrin or cucurbituril, although a macromolecule carrying a threadable ring also qualifies. Threading a simple polyethylene chain needs a ring of at least 24 members.",
