25diterpenes — Hydrocarbons or their derivatives containing four isoprene units, hence containing 20 carbon atoms and four branched methyl groups; e.g., vitamin A, retinene, aconitine …
26monoterpenes — Hydrocarbons or their derivatives formed by the condensation of two isoprene units, and therefore containing 10 carbon atoms; e.g., camphor; often containing a cyclic structure …
27tetraterpenes — Hydrocarbons or their derivatives formed by the condensation of eight isoprene units ( i.e., four terpenes) and therefore containing 40 carbon atoms; e.g., various carotenoids …
28triterpenes — Hydrocarbons or their derivatives formed by the condensation of six isoprene units (equivalent to three terpene units) and containing, therefore, 30 carbon atoms; e.g., squalene, certain steroids, cardiac glycosides …
