(3S,5R,8S)-5,8-Epoxy-5,8-dihydro-beta,beta-caroten-3-ol
IUPAC 名称
(2S,6S,7aR)-4,4,7a-trimethyl-2-[(2E,4E,6E,8E,10E,12E,14E,16E)-6,11,15-trimethyl-17-(2,6,6-trimethylcyclohex-1-en-1-yl)heptadeca-2,4,6,8,10,12,14,16-octaen-2-yl]-2,4,5,6,7,7a-hexahydro-1-benzofuran-6-ol
描述
(3s,5r,8s)-5,8-epoxy-5,8-dihydro-beta,beta-caroten-3-ol 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 (3s,5r,8s)-5,8-epoxy-5,8-dihydro-beta,beta-caroten-3-ol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). (3s,5r,8s)-5,8-epoxy-5,8-dihydro-beta,beta-caroten-3-ol can be found in guava, which makes (3s,5r,8s)-5,8-epoxy-5,8-dihydro-beta,beta-caroten-3-ol a potential biomarker for the consumption of this food product.
