Types Terpenes may be classified by the number of terpene units in the molecule; a prefix in the name indicates the number of terpene units needed to assemble the molecule. Although the structures of terpenoids are rationalized as derivatives of isoprene 2-methyl-1,3-butadieneisoprene is not involved in the biosynthesis. Bicyclic terpenes. Examples of monoterpenes are: geraniol, limonene and terpineol. Terpenes, as a constituent of essential oils, have long been used in human culture. Annual Review of Plant Biology. Terpenes are derived biosynthetically from units of isopentenyl pyrophosphate.

    Terpenes may be classified by the number of isoprene units in the molecule; a prefix Examples of diterpenes and diterpenoids are cafestol, kahweol, cembrene . Campesterol; beta Sitosterol; gamma sitosterol; Stigmasterol. The isoprene units in terpenes do not come from isoprene.

    They come from isopentenyl pyrophosphate. Isopentenyl pyrophosphate (5 carbons) comes.

    Some peculiar diterpenes are cembrene, taxadiene, cafestol, etc. like lycopene, monocyclic like gammacarotene, and bicyclic like alpha- and beta-​carotenes.

Formally, in biosynthesis of terpenes, two or more isoprene molecules are linked to one another. The head of one isoprene molecule could link with the head of another isoprene molecule. see also isoprene unit.

    Diterpenes, (four isoprene units), terpenes with formula (C20H32) Neocembrene, Neocembrene A, Cembrene A, (C20H32), diterpene, macrocycle, metabolite, (derived from (a sterol 3-beta-D-glucoside, a monosaccharide derivative).
    Terpenes are derived biosynthetically from units of isopentenyl pyrophosphate.

    Terpenes provide a number of valued functions for the living organisms that produce them, in addition to being building blocks for other molecules. Diterpenes also form the basis for biologically important compounds such as retinol, retinal, and phytol.

    1. Sometimes terpenoids are added to proteinssuch as to enhance their attachment to the cell membrane ; this is known as isoprenylation. Acyclic linear, cis and trans forms Monocyclic single ring Bicyclic 2 rings Iridoids cyclopentane ring Iridoid glycosides iridoids bound to a sugar Steroids 4 rings.

    2. Many, obviously different hydrocarbons have not been distinguished for a long time and have been assigned the same names, while on the other hand, probably identical substances from different sources have often been specified by different names.

    3. Besides the therapeutic effects provided by the terpenes to the plants containing them, essential oils have industrial significance in the manufacture of paints and varnishes.
