cis-Violaxanthin
IUPAC 名称
6-[(1E,3Z,5E,7E,9E,11E,13E,15E,17E)-18-{4-hydroxy-2,2,6-trimethyl-7-oxabicyclo[4.1.0]heptan-1-yl}-3,7,12,16-tetramethyloctadeca-1,3,5,7,9,11,13,15,17-nonaen-1-yl]-1,5,5-trimethyl-7-oxabicyclo[4.1.0]heptan-3-ol
描述
Cis-violaxanthin 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. Cis-violaxanthin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Cis-violaxanthin can be found in ginkgo nuts and potato, which makes cis-violaxanthin a potential biomarker for the consumption of these food products.
