Bisabolene

Bisabolenes are a group of closely related natural chemical compounds which are classified as sesquiterpenes. Bisabolenes are produced from farnesyl pyrophosphate (FPP)[1] and are present in the essential oils of bisabol, and of a wide variety of other plants including cubeb, lemon, and oregano. Various derivates also function as pheromones in different insects, such as stink bugs[2] and fruit flies.[3] Bisabolenes are produced by several fungi, though their biological role in that group of organisms remains unclear.[4]

Three isomers are known, α-, β-, and γ-bisabolene,[5][6] which differ by the positions of the double bonds.

Uses

Bisabolenes are intermediates in the biosynthesis of many other natural chemical compounds,[7] including hernandulcin, a natural sweetener. β-Bisabolene has a balsamic odor[8] and is approved in Europe as a food additive.

Bisabolene has been identified as a biologically producible precursor to a diesel fuel alternative and/or cold weather additive bisabolane. [9]

gollark: In that case, AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA.
gollark: Okay, I now know it is a joke.
gollark: No. Do not animation.
gollark: osmarks.tk's experiment pages are just HTML/CSS/JS with no title bar or comment box or anything, plus metadata, and the blog stuff is Markdown. The static site generator compiles the markdown to HTML, and puts the HTML into templates, embeds styles and stuff, adds the achievement system code, and all that sort of thing, and produces HTML/CSS/JS for upload to my server.
gollark: APNG good, MP4 good, etc.
