Common NameLutein 5,6-epoxide
DescriptionLutein 5,6-epoxide, also known as taraxanthin, belongs to the class of organic compounds known as xanthophylls. These 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. Thus, lutein 5,6-epoxide is considered to be an isoprenoid lipid molecule. Lutein 5,6-epoxide is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, Lutein 5,6-epoxide has been detected, but not quantified in, several different foods, such as common grapes, rices, sunflowers, dandelions, and garden tomato (var.). This could make lutein 5,6-epoxide a potential biomarker for the consumption of these foods. Lutein 5,6-epoxide is found in Brassica napus, Brassica oleracea, Caltha palustris, Camellia sasanqua, Citrus junos, Citrus wilsonii, Cladonia firma, Cladonia turgida, Cladophora fracta, Cucurbita maxima, Cuscuta australis , Cytisus scoparius, Diospyros kaki, Equisetum palustre, Eutreptiella gymnastica, Holothuria tubulosa, Impatiens nolitangere, Metasequoia glyptostroboides, Mimosa aculeaticarpa, Sohaghnum palustre, Terminalia catappa, Tussilago farfara , Umbilicaria rigida and Urtica dioica . An epoxycarotenol derivative of lutein.
