Some natural rubber sources, called gutta percha, are composed of trans-1,4-polyisoprene, a structural isomer that has similar, but not identical, properties. https://doi.org/10.1351/goldbook.I03306. It may also protect plants against large fluctuations in leaf temperature. No adequate human studies of the relationship between isoprene exposure and human cancer have been reported. CopyCopied, InChI=1S/C5H8/c1-4-5(2)3/h4H,1-2H2,3H3 Furthermore, isoprene forms secondary organic aerosols through photooxidation with OH radicals which also have wide-ranging health effects, particularly for the respiratory tract, and reduce visibility due to light scattering effects.

It is commonly used in industry, is an important biological material, and can be a harmful environmental pollutant and toxicant when present in excess quantities. C. G. Williams named the compound in 1860 after obtaining it from thermal decomposition (pyrolysis) of natural rubber; he correctly deduced the empirical formula C5H8. give the IUPAC equivalent of the following trivial names: ethylene, propylene, isobutylene and isoprene. The United States Department of Transportation considers isoprene a hazardous material and requires special marking, labeling, and transportation for it. Isoprene emission may help trees use to combat stress. With an accout for my.chemeurope.com you can always see everything at a glance – and you can configure your own website and individual newsletter. Examples of isoprenoids include carotene, phytol, retinol (vitamin A), tocopherol (vitamin E), dolichols, and squalene. MEDIUM. About 95% of isoprene production is used to produce cis-1,4-polyisoprene—a synthetic version of natural rubber. It is produced by many plants and animals (including humans).
