All-trans-3,4-didehydrolycopene is a member of the class of compounds known as carotenes. Carotenes 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, all-trans-3,4-didehydrolycopene is considered to be an isoprenoid lipid molecule. All-trans-3,4-didehydrolycopene can be found in a number of food items such as kale, giant butterbur, citrus, and ginkgo nuts, which makes all-trans-3,4-didehydrolycopene a potential biomarker for the consumption of these food products.
