Luteoxanthin
IUPAC 名称
2-[(2E,4E,6E,8E,10E,12E,14E,16E)-17-{4-hydroxy-2,2,6-trimethyl-7-oxabicyclo[4.1.0]heptan-1-yl}-6,11,15-trimethylheptadeca-2,4,6,8,10,12,14,16-octaen-2-yl]-4,4,7a-trimethyl-2,4,5,6,7,7a-hexahydro-1-benzofuran-6-ol
描述
Luteoxanthin 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. Luteoxanthin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Luteoxanthin can be found in a number of food items such as yellow bell pepper, pepper (c. annuum), green bell pepper, and apple, which makes luteoxanthin a potential biomarker for the consumption of these food products.
