(3R,3'R,15Z)-Zeaxanthin
IUPAC 名称
4-[(1E,3E,5E,7E,9E,11E,13E,15E,17E)-18-(4-hydroxy-2,6,6-trimethylcyclohex-1-en-1-yl)-3,7,12,16-tetramethyloctadeca-1,3,5,7,9,11,13,15,17-nonaen-1-yl]-3,5,5-trimethylcyclohex-3-en-1-ol
描述
Beta,beta-carotene-3,3'-diol, also known as (3r,3's)-zeaxanthin or anchovixanthin, 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. Beta,beta-carotene-3,3'-diol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Beta,beta-carotene-3,3'-diol can be found in channel catfish, crustaceans, and fishes, which makes beta,beta-carotene-3,3'-diol a potential biomarker for the consumption of these food products.
