Biosynthesis of cocaine
The biosynthesis of cocaine is the natural metabolic process by which the coca plant (Erythroxylum species) produces cocaine, a tropane alkaloid, through a multi-step enzymatically catalyzed pathway beginning with ornithine or arginine and culminating in the formation of the cocaine metabolite benzoylecgonine. The biosynthesis of cocaine has long attracted the attention of biochemists and organic chemists.
