Common Nameγ-carotene
ClassSmall Molecule
Descriptionγ-carotene is a carotenoid, and is a biosynthetic intermediate for cyclized carotenoid synthesis in plants. It is formed from cyclization of lycopene by lycopene cyclase epsilon. Along with several other carotenoids, γ-carotene is a vitamer of vitamin A in herbivores and omnivores. Carotenoids with a cyclized, beta-ionone ring can be converted to vitamin A, also known as retinol, by the enzyme Beta-carotene 15,15'-dioxygenase; however, the bioconversion of gamma-carotene to retinol has not been well-characterized . γ-carotene can be found in a number of food items such as devilfish, bilberry, orange bell pepper, and rosemary, which makes γ-carotene a potential biomarker for the consumption of these food products.

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.
