Metabolite Identification
Common NameLycopene
DescriptionLycopene (molecular formula: C40H56) is a bright red carotenoid pigment. It is a phytochemical found in tomatoes and other red fruits. Lycopene is the most common carotenoid in the human body and is one of the most potent carotenoid antioxidants. Its name is derived from the tomato's species classification, Solanum lycopersicum. Lycopene is a terpene assembled from 8 isoprene units. Lycopene is the most powerful carotenoid quencher of singlet oxygen. Singlet oxygen from ultraviolet light is a primary cause of skin aging (Wikipedia ).

Chemical Taxonomy
Description 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.

Enzymes

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.
