Common Namezeta-carotene
Description7,7',8,8'-Tetrahydrolycopene, also known as zeta-carotene or carotene, zeta, 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, 7,7',8,8'-tetrahydrolycopene is considered to be an isoprenoid lipid molecule. 7,7',8,8'-Tetrahydrolycopene is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 7,7',8,8'-Tetrahydrolycopene exists in all living organisms, ranging from bacteria to humans. zeta-carotene is found in Averrhoa carambola, Brassica napus, Calendula officinalis, Chlorella vulgaris, Citrus maxima, Crocus sativus, Lonicera japonica, Prunus armeniaca, Rhodospirillum rubrum, Rosa rugosa and Rosa villosa. zeta-carotene was first documented in 1971 (PMID: 16657570). The all-trans-isomer of zeta-carotene (PMID: 1396714).
