Common NameCedarwood oil terpenes
Descriptionalpha-Cedrene or Cedrene, also known as Cedarwood oil terpenes, belongs to the class of organic compounds known as cedrane and isocedrane sesquiterpenoids. These are sesquiternoids with a structure based on the cedrane or the isocedrane skeleton. Cedrane is a tricyclic molecules a 3,6,8,8-tetramethyl-1H-3a,7-methano-azulene moiety. Isocedrane is a rearranged cedrane arising from the migration of methyl group moved from the 6-position to the 4-position. Cedarwood oil terpenes is possibly neutral. Cedrene is a naturally occurring tricyclic sesquiterpene found in the essential oil of cedar. There are two known Cedrene isomers including α- and β-Cedrene which differ in the position of a double bond. alpha-Cedrene is one of the many sesquiterpenes found in cannabis plants and their essential oils (PMID:6991645 ). Sesquiterpenoides are terpenes that contain 15 carbon atoms and are comprised of three isoprene units. The biosynthesis of sesquiterpenes is known to occur mainly through the mevalonic acid pathway (MVA), in the cytosol. However, recent studies have found evidence of pathway crosstalk with the methyl-eritritol-phosphate (MEP) pathway in the cytosol. Farnesyl diphosphate (FPP) is a key intermediate in the biosynthesis of cyclic sesquiterpenes. FPP undergoes several cyclation reactions to yield a diverse number of cyclic arrangements.
