Concept Introduction:
Terpenes are made by joining five-carbon units, usually in a head to tail-fashion.
Monoterpenes are those terpenes with two isoprene units-have 10 carbons, sesquiterpenes have 15 carbons, diterpenes have 20 carbons, triterpenes have 30 carbons and tetraterpenes have 40 carbons.
Isopentenyl pyrophosphate (isoprene) is the five-carbon compound used for the biosynthesis of terpenes.
Isoprene unit:
