Cannabis Compound Identification
Common Namebeta-Carotene
Descriptionbeta-Carotene, also known as b-karotin or β-carotene, belongs to the class of organic compounds known as carotenes. These are a type of unsaturated hydrocarbons containing eight consecutive isoprene units. They 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. Thus, beta-carotene is considered to be an isoprenoid lipid molecule. beta-Carotene is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. beta-Carotene is expected to be in Cannabis as all living plants are known to produce and metabolize it.

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.
Gene Name:

Q9HAY6
Molecular weight:
62636.69
General function:
Secondary metabolites biosynthesis, transport and catabolism
Specific function:
Asymmetrically cleaves beta-carotene at the 9',10' double bond resulting in the formation of beta-apo-10'-carotenal and beta-ionone. Besides beta-carotene, lycopene is also oxidatively cleaved. The apocarotenals formed by this enzyme may be the precursors for the biosynthesis of retinoic acid or exert unknown physiological effects.
