Mutachrome
IUPAC 名称
4,4,7a-trimethyl-2-[(2E,4E,6E,8E,10E,12E,14E,16E)-6,11,15-trimethyl-17-(2,6,6-trimethylcyclohex-1-en-1-yl)heptadeca-2,4,6,8,10,12,14,16-octaen-2-yl]-2,4,5,6,7,7a-hexahydro-1-benzofuran
描述
Mutatochrome, also known as citroxanthin, 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. Thus, mutatochrome is considered to be an isoprenoid lipid molecule. Mutatochrome is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Mutatochrome can be found in a number of food items such as passion fruit, citrus, sweet orange, and pepper (c. frutescens), which makes mutatochrome a potential biomarker for the consumption of these food products. Mutatochrome (5,8-epoxy-β-carotene) is a carotenoid. It is the predominant carotenoid in the cap of the bolete mushroom Boletus luridus .
