Abstract
Abstract
The chemical structure of naturally occurring cis-polyisoprene isolated from Solidago altissima was determined by 13C NMR spectroscopy. The alignment of the isoprene units in the polymer was estimated to be in the order: dimethylallyl terminal unit, three trans units, about 1000 to 2200 of internal cis units, and a cis allyl alcohol terminal unit. This demonstrates that the biosynthesis of cis-polyisoprene in this higher plant starts from trans,trans,trans-geranylgeranyl pyrophosphate.
