15,15'-dihydroxy-β-carotene
IUPAC 名称
(1E,3E,5E,7E,11E,13E,15E,17E)-3,7,12,16-tetramethyl-1,18-bis(2,6,6-trimethylcyclohex-1-en-1-yl)octadeca-1,3,5,7,11,13,15,17-octaene-9,10-diol
描述
15,15'-dihydroxy-beta-carotene, also known as retinal-pinacol or 15,15'-dihydro-15,15'-dihydroxy-b,b-carotene, 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. 15,15'-dihydroxy-beta-carotene is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 15,15'-dihydroxy-beta-carotene can be found in a number of food items such as white lupine, breadfruit, brussel sprouts, and black salsify, which makes 15,15'-dihydroxy-beta-carotene a potential biomarker for the consumption of these food products.
