GENERAL DESCRIPTION OF TERPENE
A class of naturally occurring compounds mainly in plants as constituents of essential oils whose carbon skeletons are composed exclusively of isoprene C5 units (CH2=C(CH3)-CH=CH2). Most terpenes are hydrocarbons having molecular formula (C5H8)n in a cyclic or acyclic, saturated or unsaturated structure, while the terpenoids are oxygen-containing analogues of the terpenes such as alcohols, aldehydes or ketones containing hydroxyl groups or carbonyl groups. Several vitamines, hormones, flavour and flagrances and latex are terpenoids. Terpenes containing 30 or more carbons are usually formed by the fusion of two terpene precursors in a regular pattern, usually head-to-tail appears to be violated. They are differ from one another not only in functional groups but also in their basic carbon skeletons. Terpenes are employed mainly the fragrance and flavour purpose, as well as in the pharmaceutical and chemical industries. They are classified by the number of isoprene units:
