Chemical Information
FooDB Namealpha-Cryptoxanthin
Descriptionalpha-Cryptoxanthin, also known as α-cryptoxanthin, 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. alpha-Cryptoxanthin is an extremely weak basic (essentially neutral) compound (based on its pKa).
