IUPAC 名称
(1R,2R,4S)-1-[(1E,3E,5E,7E,9E,11E,13E,15E,17E)-18-[(1S,4S,6R)-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]-2,6,6-trimethylcyclohexane-1,2,4-triol
描述
Latoxanthin 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. Latoxanthin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Latoxanthin can be found in a number of food items such as red bell pepper, yellow bell pepper, orange bell pepper, and pepper (c. annuum), which makes latoxanthin a potential biomarker for the consumption of these food products.
