Key part of a macrocyclic component: molecular ring (cycle) large enough to be threaded onto a linear subchain of a threading component.
Note: A threadable ring (cycle) should be distinguished from other smaller, non-threadable rings within a complex macrocyclic component, such as benzene, cyclooctane, or similar rings.
