Neurosporene, also known as all-trans-neurosporene or 7,8-dihydro-ψ,ψ-carotene, 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, neurosporene is considered to be an isoprenoid lipid molecule. Neurosporene can be found in a number of food items such as chicory, poppy, silver linden, and towel gourd, which makes neurosporene a potential biomarker for the consumption of these food products. Neurosporene can be found primarily in blood and breast milk. Neurosporene is a carotenoid pigment. It is an intermediate in the biosynthesis of lycopene and a variety of bacterial carotenoids . Neurosporene is a triterpenoid carotenoid identified in human plasma, (PMID: 1416048), serum (PMID: 1416048), milk (PMID: 9164160), and tissues of the human eye (PMID: 11180970).
