Where it comes from
Biosynthetic pathway: Terpenoid pathway — plants build them from identical five-carbon blocks.
Why it sits where it does
A fifteen-carbon sesquiterpene with a very compact three-ring skeleton. The closed structure makes it unusually stable chemically.
Where else you meet it
Pine resin, rosin, and many conifer wood oils.
