Biosyntesen af de forskellige molekyler (terpener, gibberelliner, cholesterol osv.) sker ikke direkte ud fra isopren, men via en kompleks række af reaktioner.
Isopren lader til at fungere som en [[aerosol]] katalysator og de dannede aerosoler er [[hygroskopisk]]e og lader til at danne [[sky]]er og [[tåge]]. Det viser sig at mange [[plante]]r danner store mængder isopren.

"The king emitters are [[eg|oaks]]," Wennberg says. "And the isoprene they emit is one of the reasons that the [[Smoky Mountains]] appear smoky."..."And isoprene only comes from plants. They make hundreds of millions of tons of this chemical...for reasons that we still do not fully understand."..."

Her exhaustive work represents a major step toward a complete picture of how human activity affects the global ecosystem.
