Carotenoids, the C40 tetraterpenoids derived from head-to-tail condensation of eight isoprenoid units, are notable for their wide distribution, structural diversity, and various functions.
These are produced from 8 isoprene molecules and contain 40 carbon atoms and are also known as tetraterpenoids with polyisoprenoid structure having a long conjugated double bond system forming the backbone of the molecule, which may be terminated by cyclic end groups that contain oxygen-bearing substitutes.
