In research published in the Proceedings of the National Academy of Sciences in 2012, Donahue and colleagues showed conclusively that organic molecules given off by pine trees, called alpha - pinene, are chemically transformed multiple times in the highly oxidizing environment of the atmosphere.

In the current work, the team filled the chamber with sulfur dioxide and pinnanediol (an oxidation product of alpha - pinene) and then generated hydroxyl radicals (the dominant oxidant in Earth's atmosphere).

Companies such as NaPro Research and Phylos have begun working out how to breed cannabis varieties with specific levels of popular terpenes — including limonene and pinene as well as myrcene, which some believe potentiates THC's effects — for a designed experience.

To accurately predict how alpha - pinene reacts in the troposphere, and thus how it affects climate and air quality, researchers need a detailed understanding of its molecular structure.

The main monoterpene is alpha - pinene, of which forests release about 50 trillion grams each year into the atmosphere's lowest layer, the troposphere.

Now that the researchers have the structure of alpha - pinene, they are better able to model the first steps of nature's aerosol formation in the atmosphere.

For this project, Isaacman - VanWertz studied the smell of pine, which is made of an organic compound known as pinene.

Isaacman - VanWertz picked pinene because it has been extensively studied, so he could use previous work to make sense of his observations.

«We have focused our efforts on the oxidation of α - pinene, because it accounts for about half of global monoterpene emissions,» explains Dr. Mikael Ehn from the University of Helsinki, who is the first author of this study and did the pioneering work for the discovering of ELVOCs.

On the other hand, β - pinene, myrcene and isoprene, produce much less ELVOC's, which are an important biogenic sources for the formation of particles in the atmosphere,» emphasizes Dr. Torsten Berndt of TROPOS, who was involved in all three publications.

This includes the role of oxidized volatile organic compounds, such as limonene and alpha - pinene, the typical scents of the citrus fruits and coniferous forests, in aerosol formation.

This shows that the role of ozone (the oxidant of α - pinene and other monoterpenes) has been underestimated.

In another set of experiments, they coated the sulfate particles with atmospheric products of α - pinene, the gas responsible for that distinctive pine tree smell, and then added IEPOX.

The main components of frankincense oil are ketonic alcohol (olibanol), resinous matters (30 to 60 percent) and terpenes such as a-and p - pinene, camphene, dipentene and phellandrene.12 It also contains alpha pinene, actanol, bornyl acetate, linalool, octyl acetate, incensole and incensyl acetate.13

lauri folii), consisting of 45 % eucalyptol, 12 % other terpenes, 8 - 12 % terpinyl acetate, 3 — 4 % sesquiterpenes, 3 % methyleugenol, and other α - and β - pinenes, phellandrene, linalool, geraniol, and terpineol.

Effect of pellet boiler exhaust on secondary organic aerosol formation from α - pinene.

In collaboration with the Chinese Academy of Sciences, researchers provided molecular - level insights into how alpha - pinene, a compound emitted in large quantities by pine trees, helps form new atmospheric aerosols.

I think these kinds of «anti-transpiration» sprays are made with pinene, so its all natural and non-toxic, dries to a medium gloss, and, in this case, locks the glitter in place.
