| carotenoid | <biochemistry> Accessory lipophilic photosynthetic pigments in plants and bacteria, including carotenes and xanthophylls, red, orange or yellow, with broad absorption peaks at 450-480nm. Act as secondary light harvesting pigments, passing energy to chlorophyll and as protective agents, preventing photoxidation of chlorophyll. Found in chloroplasts and also in plastids in some nonphotosynthetic tissues, for example carrot root. (18 Nov 1997) |

| carotenoids | Generic term for a class of carotenes and their oxygenated derivatives (xanthophylls) consisting of 8 isoprenoid units joined so that the orientation of these units is reversed at the centre, placing the two central methyl groups in a 1,6 relationship in contrast to the 1,5 of the others. All carotenoids may be formally derived from the acyclic C40H56 structure (part IA, known as lycopene, of the accompanying group of structures) with its long central chain of conjugated double bonds by hydrogenation, dehydrogenation, oxidation, cyclization, or combinations of these. Included as carotenoids are some compounds arising from certain rearrangements or degradations of the carbon skeleton (structure IB), but not retinol and related C20 compounds. The nine-carbon end-groups may be acyclic with 1,2 and 5,6 double bonds (as in structure IA) or cyclohexanes with a single double bond at 5,6 or 5,4, or cyclopentanes or aryl groups; these are now designated by Greek letter prefixes (illustrated in part II of the accompanying group of structures) preceding "carotene" (a and d, which are used in the trivial names alpha-carotene and d-carotene, are not used for that reason). Suffixes (-oic acid, -oate, -al, -one, -ol) indicate certain oxygen-containing groups (acid, ester, aldehyde, ketone, alcohol); all other substitutions appear as prefixes (alkoxy-, epoxy-, hydro-, etc.). The configuration about all double bonds is trans unless cis and locant numbers appear. The prefix retro-is used to indicate a shift of one position of all single and double bonds; apo-indicates shortening of the molecule. Many carotenoids have anticancer activities. (05 Mar 2000) |

| carotenoid |
Red to yellow pigments responsible for the characteristic colour of many plant organs or fruits, such as tomatoes, carrots, etc. Oxidation products of carotene are called xanthophylls. Carotenoids serve as light-harvesting molecules in photosynthetic assemblies and also play a role in protecting prokaryotes from the deleterious effects of light.
