isoprene

 [i´so-prēn]
an unsaturated, branched-chain, five-carbon hydrocarbon that is the molecular unit of isoprenoid compounds.

i·so·prene

(ī'sō-prēn),
2-Methyl-1,3-butadiene; an unsaturated five-carbon hydrocarbon with a branched chain, which in the plant and animal kingdom is used as the basis for the formation of isoprenoids, for example, terpenes, carotenoids and related pigments, rubber. Fat-soluble vitamins either are isoprenoid or have isoprenoid side chains; steroids are synthesized via isoprenoid intermediates, as are ubiquinone, dolichol, and prenylated proteins.
