1,8-Cineole synthase (EC 4.2.3.108, 1,8-cineole cyclase, geranyl pyrophoshate:1,8-cineole cyclase, 1,8-cineole synthetase) is an enzyme with systematic name geranyl-diphosphate diphosphate-lyase (cyclizing, 1,8-cineole-forming). [1] [2] [3] [4] [5] This enzyme catalyses the following chemical reaction
This enzyme requires Mn2+ or Zn2+. Geranyl diphosphate first isomerizes to (S)-linalyl diphosphate which ionises to the alpha-terpinyl cation which reacts with water to form the product. [6]
Eucalyptol is a monoterpenoid colorless liquid, and a bicyclic ether. It has a fresh camphor-like odor and a spicy, cooling taste. It is insoluble in water, but miscible with organic solvents. Eucalyptol makes up about 70–90% of eucalyptus oil. Eucalyptol forms crystalline adducts with hydrohalic acids, o-cresol, resorcinol, and phosphoric acid. Formation of these adducts is useful for purification.
Sabinene is a natural bicyclic monoterpene with the molecular formula C10H16. It is isolated from the essential oils of a variety of plants including Marjoram, holm oak (Quercus ilex) and Norway spruce (Picea abies). It has a strained ring system with a cyclopentane ring fused to a cyclopropane ring.
Farnesyl pyrophosphate (FPP), also known as farnesyl diphosphate (FDP), is an intermediate in the biosynthesis of terpenes and terpenoids such as sterols and carotenoids. It is also used in the synthesis of CoQ, as well as dehydrodolichol diphosphate.
