Chemical Information
FooDB Namegamma-Terpinene
Descriptiongamma-Terpinene belongs to the class of organic compounds known as menthane monoterpenoids. Monoterpenoids are terpenes that contain 10 carbon atoms and are comprised of two isoprene units. The biosynthesis of monoterpenes is known to occur mainly through the methyl-eritritol-phosphate (MEP) pathway in the plastids. Geranyl diphosphate (GPP) is a key intermediate in the biosynthesis of cyclic monoterpenes. GPP undergoes several cyclization reactions to yield a diverse number of cyclic arrangements. Menthanes are monoterpenoids with a structure based on the o-, m-, or p-menthane backbone. P-menthane consists of the cyclohexane ring with a methyl group and an isopropyl group at the 1 and 4 ring position, respectively. The o- and m- menthanes are much rarer, and presumably arise by alkyl migration of p-menthanes. gamma-Terpinene is one of 4 isomeric monoterpenes differing in the positions of their two double bonds (alpha- and beta-terpinene being the others). In gamma-terpinene the double bonds are at the 1- and 4-positions of the p-menthane skeleton.
