b-Cryptoxanthin palmitate
IUPAC 名称
3,5,5-trimethyl-4-[(1E,3E,5E,7E,9E,11E,13E,15E,17E)-3,7,12,16-tetramethyl-18-(2,6,6-trimethylcyclohex-1-en-1-yl)octadeca-1,3,5,7,9,11,13,15,17-nonaen-1-yl]cyclohex-3-en-1-yl hexadecanoate
描述
B-cryptoxanthin palmitate 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. B-cryptoxanthin palmitate is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). B-cryptoxanthin palmitate can be found in papaya, which makes B-cryptoxanthin palmitate a potential biomarker for the consumption of this food product.
