  "term": "Tetraterpenoids",
  "field": "Chemistry",
  "definition": "A class of terpenoids derived from eight isoprene units, resulting in compounds with 40 carbon atoms. These molecules are formed by the head-to-head coupling of two C20 geranylgeranyl pyrophosphate units. Carotenoids, such as beta-carotene and lycopene, are well-known tetraterpenoids responsible for vibrant colors in plants and animals.",
