Sterols, Carotenoids, and Polyprenols

  • John D. Weete


Isoprenoid substances comprise a large, complex, and important group of natural products, most of which are produced by plants. The basic building block of these substances is isoprene (2-methyl-1,3-butadiene): Open image in new window Condensation of the pyrophosphorylated form of isoprene, isopentenyl-pyrophosphate (IPP), with its isomer dimethyl-allyl-pyrophosphate (DMPP) followed by subsequent additions of IPP to the growing chain, and in some cases cyclization, leads to the formation of the various classes of compounds called isoprenoids or terpenoids: monoterpenes (C10)/ sesquiterpenes (C15), diterpenes (C20), and C30 to C85 compounds that includes triterpenes (sterols), carotenes, xanthophylls, penta- and hexacyclic alkaloids, rubber, and the polyprenols. This chapter is concerned only with the occurrence of sterols, carotenoids, and polyprenols in fungi.
