  "term": "Carrier atom",
  "field": "Chemistry",
  "definition": "A reaction participant, named in the IUPAC system for symbolic representation of reaction mechanisms, that is neither a core atom, the primary reference atom of the mechanistic change, nor a peripheral atom, a secondary reference atom that ends up inside the same molecule as the core atom. A carrier atom shuttles groups onto and off that molecule without itself becoming covalently attached to it.",
