isoprenoidTail-to-tail coupling of isoprenoids…joining of two equivalents of farnesyl pyrophosphate. In the 1960s the British chemist John W. Cornforth showed that omitting a necessary reductant in the enzyme system that promotes the formation of squalene causes an unusual compound containing a three-membered ring, called presqualene pyrophosphate, to accumulate. (OPP represents the pyrophosphate group.)

…leads to the 15-carbon compound farnesyl pyrophosphate—from which the sesquiterpenes are derived—which in turn is converted to the 20-carbon precursor of the diterpenes. All these reactions produce substances in which the isoprene units are joined head-to-tail; many of the larger isoprenoid molecules (triterpenes and tetraterpenes) are not built up by…
