Cembrene A itself has little importance as a chemical entity, being a trail pheromone for termites;[2] however, the chemical structure of cembrene is central to a very wide variety of other natural products found both in plants and in animals.[3]
Cembrenes are biosynthesized by macrocyclization of geranylgeranyl pyrophosphate.[3]
