http://dbpedia.org/ontology/abstract Phytoene (/ˈfaɪtoʊiːn/) is a 40-carbon intPhytoene (/ˈfaɪtoʊiːn/) is a 40-carbon intermediate in the biosynthesis of carotenoids. The synthesis of phytoene is the first committed step in the synthesis of carotenoids in plants. Phytoene is produced from two molecules of geranylgeranyl pyrophosphate (GGPP) by the action of the enzyme phytoene synthase. The two GGPP molecules are condensed together followed by removal of diphosphate and proton shift leading to the formation of phytoene. Dietary phytoene and phytofluene are found in a number of human tissues including the liver, lung, breast, prostate, colon, and skin. Accumulation of these carotenoids in the skin may protect the skin by several mechanisms: acting as UV absorbers, as antioxidants, and as anti-inflammatory agents.oxidants, and as anti-inflammatory agents. , Fytoen är en 40-kols tetraterpenoid som utFytoen är en 40-kols tetraterpenoid som utgör det första steget i växternas biosyntes av karotenoider.

Genom födan får människan i sig fytoen och fytofluen som återfinns i många olika vävnader som lever, hjärta och hud.
