ter·pene

(ter'pēn),
One of a class of hydrocarbons with an empiric formula of C10H16, occurring in essential oils and resins. Acyclic terpenes may be regarded as isomers and polymers of isoprene units; cyclic forms include menthane, bornane, and camphene. Terpenes containing 15, 20, 30, 40, etc., carbon atoms are called sesquiterpenes, diterpenes, triterpenes, tetraterpenes, etc.
