The biosynthesis of terpene compounds

From Wallach's isoprene rule to Ruzieka's biogenetic isoprene rule, the monoterpenes and sesquiterpenes have played a significant role in the development of basic concepts concerning the origin of all terpenoid compounds. Yet, while our understanding of the biosynthesis of higher terpenoids, such as steroids, has flourished progress in the biochemistry of monoterpenes and sesquiterpenes has been relatively slow--due in large part to the chemical nature of the mono- and sesquiterpenes (volatility, instability, and so forth) and to the experimental difficulties associated with the plants that produce these compounds.
