| Description | Cucurbitaxanthin A 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. Cucurbitaxanthin A is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Cucurbitaxanthin A has been detected, but not quantified in, several different foods, such as yellow bell peppers, fruits, pepper (c. Annuum), winter squash, and orange bell peppers. 2-(4-{7-hydroxy-3a,6,6,9a,11a-pentamethyl-1h,2h,3h,5h,5ah,7h,8h,9h,11h-cyclopenta[a]phenanthren-1-yl}pentylidene)propane-1,3-diol is found in Ganoderma sinense. This could make cucurbitaxanthin a a potential biomarker for the consumption of these foods. |
