Plants protect themselves against self-induced air pollutants

Trees and other plants release isoprene into the atmosphere. Oxidation processes result in compounds that are harmful to plants. Researchers at the University of Innsbruck have now uncovered a mechanism by which plants protect ...

How severe drought influences ozone pollution

From 2011 to 2015, California experienced its worst drought on record, with a parching combination of high temperatures and low precipitation. Drought conditions can have complicated effects on ozone air quality, so to better ...

Probing water's skin

From the wind-whipped surface of the open ocean, to trillions of tiny water drops in clouds, the air-water interface—water's skin— is the site for crucial natural processes, including ocean-atmosphere exchange and cloud ...

A chemical criterion for rating movies

A measurable criterion now exists for determining the age rating of films. A group of scientists at the Max Planck Institute for Chemistry in Mainz has found that the concentration of isoprene in cinema air correlates with ...

Isoprene (short for isoterpene), or 2-methyl-1,3-butadiene, is a common organic compound with the formula CH2=C(CH3)CH=CH2. Under standard conditions it is a colorless liquid. However, this compound is highly volatile because of its low boiling point.

Isoprene (C5H8) is the monomer of natural rubber and also a common structure motif to an immense variety of other naturally occurring compounds, collectively termed the isoprenoids. Molecular formula of isoprenoids are multiples of isoprene in the form of (C5H8)n, and this is termed the isoprene rule. The functional isoprene units in biological systems are dimethylallyl diphosphate (DMADP) and its isomer isopentenyl diphosphate (IDP).

The singular terms “isoprene” and “terpene” are synonymous whereas the plurals “isoprenes” or “terpenes” refer to terpenoids (isoprenoids).
