ε,ε-carotene-3-diol
IUPAC 名称
3,5,5-trimethyl-4-[3,7,12,16-tetramethyl-18-(2,6,6-trimethylcyclohex-2-en-1-yl)octadeca-1,3,5,7,9,11,13,15,17-nonaen-1-yl]cyclohex-2-en-1-ol
描述
ε,ε-carotene-3-diol 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. ε,ε-carotene-3-diol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). ε,ε-carotene-3-diol can be found in a number of food items such as rambutan, brassicas, other cereal product, and kohlrabi, which makes ε,ε-carotene-3-diol a potential biomarker for the consumption of these food products.
