Metabolite Identification
Common NameAlpha-Cryptoxanthin
DescriptionAlpha-cryptoxanthin is a naturally occurring carotenoid pigment with provitamin A activity whose structure is very similar to that of beta-carotene (HMDB00561). These dietary hydroxycarotenoids have been identified in human serum, milk, and ocular tissues. Industrial production of optically active (3R,6′R)-alpha-cryptoxanthin has not yet been achieved. Little is known about the potential physiological role of alpha-cryptoxanthin.

Chemical Taxonomy
Description 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.
