Chemical Information
FooDB Name5,6-Dihydro-b,b-carotene-3,3',5,6-tetrol
Description6-epikarpoxanthin 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. 6-epikarpoxanthin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 6-epikarpoxanthin can be found in a number of food items such as italian sweet red pepper, herbs and spices, fruits, and orange bell pepper, which makes 6-epikarpoxanthin a potential biomarker for the consumption of these food products.
