IUPAC 名称
2-[(3Z,5E,13E)-3,7,12,16,20,24-hexamethylpentacosa-1,3,5,7,9,11,13,15,17,19,23-undecaen-1-yl]-1,3,3-trimethylcyclohex-1-ene
描述
γ-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.
