  "term": "Protecting group",
  "field": "Chemistry",
  "definition": "A chemical moiety temporarily introduced into a molecule to mask or block the reactivity of a specific functional group during a synthetic transformation. This allows other reactions to proceed selectively without interfering with the protected group. After the desired reaction, the protecting group is removed to regenerate the original functionality.",
