Application
异戊二烯在作为引发剂的仲丁基锂的存在下，可以与苯乙烯和甲基丙烯酸甲酯进行顺序的阴离子聚合，从而形成聚苯乙烯-嵌段-聚异戊二烯-嵌段-聚（甲基丙烯酸甲酯）（SIM）和聚异戊二烯-嵌段-聚苯乙烯-嵌段-聚（甲基） 甲基丙烯酸酯（ISM），两种不对称三嵌段三元共聚物。它也可用于聚苯乙烯-嵌段-聚异戊二烯（PS-b-PI）二嵌段共聚物的不对称合成。

This review covers the biosynthesis of the starter units of terpenoids, isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP) via the nonmevalonate pathway together with a new enzyme involved in the conversion of IPP and DMAPP, i.e type 2 IPP isomerase.

Some, but not all, plants emit isoprene. Emission of the related monoterpenes is more universal among plants, but the amount of isoprene emitted from plants dominates the biosphere-atmosphere hydrocarbon exchange. The emission of isoprene from plants affects atmospheric chemistry. Isoprene

Breath isoprene accounts for most of the hydrocarbon removal via exhalation and is thought to serve as a non-invasive indicator for assaying several metabolic effects in the human body. The primary objective of this paper is to introduce a novel
