• thujone
  • Thujone (/ˈθuːdʒoʊn/ ( listen)) is a ketone and a monoterpene that occurs naturally in two diastereomeric forms: (−)-α-thujone and (+)-β-thujone. (wikipedia.org)
  • The biosynthesis of thujone is similar to the synthesis of other monoterpenes and begins with the formation of geranyl diphosphate (GPP) from dimethylallyl diphosphate (DMAPP) and isopentenyl diphosphate (IPP), catalyzed by the enzyme geranyl diphosphate synthase. (wikipedia.org)
  • compounds
  • Powers and Lee did in 1904 another fractionation on the oil of the tree at 217-222 °C. This yielded different compounds: pinene, cineol, eugenol, methyl eugenol and a ketone called umbellulone. (wikipedia.org)
  • Other neutral compounds are oxygen-containing monoterpenes such as 6-methyl-l-heptanol, 4,6-dimethyl-l-heptanol, isopinocamphone, pinocamphone, two linalool oxides and their acetates. (wikipedia.org)
  • functional
  • General aspects of metabolism The flavouring agents evaluated at the present meeting share a number of functional groups, e.g. linear, branched, alicyclic, and unsaturated alkyl chains and alcohol, ester, and ketone groups. (inchem.org)
  • give
  • Diazomethyl isopropyl ketone reacts with methyl methacrylate to give 1-carbo-methoxy-2-isobutyryl-1-methylcyclopropane. (wikipedia.org)
  • This species is then converted to the oxime with base, and the hydroxylamine is removed to give the ketone-containing carvone. (wikipedia.org)
  • different
  • This study aimed to investigate the antinociceptive activity of (-)-carvone using different experimental models of pain and to investigate whether such effects might be involved in the nervous excitability elicited by others monoterpenes. (omicsonline.org)
