Isotopically modified

{
  "id": "MLC-T-CHM-006254",
  "term": "Isotopically modified",
  "field": "Chemistry",
  "definition": "A chemical substance in which the isotopic composition of one or more elements deviates from the natural isotopic abundance. This modification can involve enrichment in a specific isotope or depletion of another. Such compounds are used extensively as tracers in chemical reactions and biological processes to study reaction mechanisms or metabolic pathways.",
