Comment:
The diterpenoids are defined by their biosynthetic origin from the C20 precursor geranylgeraniol. They are derived from four isoprene units, but modifications occuring during the later stages in synthesis produce a veritable plethora of complex chemical structures. Diterpenoids can be arbitrarily classified according to the number of ring systems present. Thus, there are bicyclic, tricyclic and tetracyclic compounds.
