  2. Carotenoids Carotenoid, are the group of non-nitrogenous , yellow, orange, or red pigments (biochromes) that are almost universally distributed in living things. Carotenoids also called tetraterpenoids, are organic pigments that are produced by plants and algae, as well as several bacteria and fungi.
  3. Carotenoids Are the various yellow, orange, red and green pigments that are found in many fruits and vegetables. There are over 600 known carotenoids;
  4. They are split into two classes, xanthophylls (which contain oxygen) and carotenes (which are purely hydrocarbons, and contain no oxygen). All are derivatives of tetraterpenes, meaning that they are produced from 8 isoprene molecules and contain 40 carbon atoms.
  5. Carotenoids classified into two classes: Carotenes: (which are purely hydrocarbons, and contain no oxygen) Examples - alpha-carotene, beta-carotene, lycopene Xanthophylls: (which contain oxygen) Examples - beta-cryptoxanthin , Lutein , zeaxanthin TYPES OF CAROTENOIDS

  8. Diets high in carotenoid- rich fruits and vegetables are associated with reduced risk of: Cardiovascular disease some cancers many other chronic diseases Why we do need Carotenoid? Eat Orange, Red, or Yellow Food
