Metabolite Identification
Common Namebeta-Carotene-15,15'-epoxide
Descriptionbeta-Carotene-15,15'-epoxide, also known as 15,15'-epoxy-b,b-carotene or 15-ebbct, 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. beta-Carotene-15,15'-epoxide is an extremely weak basic (essentially neutral) compound (based on its pKa).

Enzymes

General function:
Secondary metabolites biosynthesis, transport and catabolism
Specific function:
Symmetrically cleaves beta-carotene into two molecules of retinal. The reaction proceeds in three stages, epoxidation of the 15,15'-double bond, hydration of the double bond leading to ring opening, and oxidative cleavage of the diol formed.
