IUPAC 名称
(1S,6R)-2,2,6-trimethyl-1-[(1E,3E,5E,7E,9E,11E,13E,15E,17E)-3,7,12,16-tetramethyl-18-[(1S,6R)-2,2,6-trimethyl-7-oxabicyclo[4.1.0]heptan-1-yl]octadeca-1,3,5,7,9,11,13,15,17-nonaen-1-yl]-7-oxabicyclo[4.1.0]heptane
描述
(5r,5'r,6s,6's)-5,6:5',6'-diepoxy-5,5',6,6'-tetrahydro-beta,beta-carotene is a member of the class of compounds known as xanthophylls. Xanthophylls are carotenoids containing an oxygenated carotene backbone. Carotenes are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. Carotenes belonging form a subgroup of the carotenoids family. Xanthophylls arise by oxygenation of the carotene backbone (5r,5'r,6s,6's)-5,6:5',6'-diepoxy-5,5',6,6'-tetrahydro-beta,beta-carotene is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). (5r,5'r,6s,6's)-5,6:5',6'-diepoxy-5,5',6,6'-tetrahydro-beta,beta-carotene can be found in sweet potato, which makes (5r,5'r,6s,6's)-5,6:5',6'-diepoxy-5,5',6,6'-tetrahydro-beta,beta-carotene a potential biomarker for the consumption of this food product.
