Limonene (/ ˈ l ɪ m ə n ˌ iː n /) is a colorless liquid aliphatic hydrocarbon classified as a cyclic monoterpene, and is the major component in the essential oil of citrus fruit peels. [1] The (+)- isomer , occurring more commonly in nature as the fragrance of oranges, is a flavoring agent in food manufacturing.
Biphenyl (also known as diphenyl, phenylbenzene, 1,1′-biphenyl, lemonene [4] or BP) is an organic compound that forms colorless crystals. Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen (the site at which it is attached) may use the prefixes xenyl or diphenylyl.
Limonene and perillyl alcohol are used in cleaning products. [13] [14] Many monoterpenes are used as food flavors and food additives, such as bornyl acetate, citral, eucalyptol, menthol, hinokitiol, camphene and limonene. [15] [16] Menthol, hinokitiol and thymol are also used in oral hygiene products. Thymol also has antiseptic and disinfectant ...
Carvone may be synthetically prepared from limonene by first treating limonene nitrosyl chloride. Heating this nitroso compound gives carvoxime. Treating carvoxime with oxalic acid yields carvone. [14] This procedure affords R-(−)-carvone from R-(+)-limonene. The major use of d-limonene is as a precursor to S-(+)-carvone. The large scale ...
[5] [6] The name "terpene" is a shortened form of "terpentine", an obsolete spelling of "turpentine". [7] Although sometimes used interchangeably with "terpenes", terpenoids (or isoprenoids) are modified terpenes that contain additional functional groups, usually oxygen-containing. [8]

Diterpenes are derived from the addition of one IPP unit to FPP to form geranylgeranyl pyrophosphate (GGPP). From GGPP, structural diversity is achieved mainly by two classes of enzymes; the diterpene synthases and cytochromes P450. Several diterpenes are produced by plants and cyanobacteria.
