  "term": "Flavans",
  "field": "Chemistry",
  "definition": "A class of flavonoid compounds based on the 2-phenylchroman skeleton, which consists of a chroman ring system substituted with a phenyl group at position 2. This parent structure lacks any ketone group or double bonds in the central C-ring, distinguishing it from related flavonoids like flavones and flavonols. Many naturally occurring flavans, such as catechins, are hydroxylated derivatives and are recognized for their antioxidant properties.",
