니코틴은 어떻게 생성되는가?
Nicotine is a potent parasympathomimetic stimulant and an alkaloid found in the nightshade family of plants. Nicotine acts as an exogenous receptor agonist at most nicotinic acetylcholine receptors (nAChRs), except at two nicotinic receptor subunits (nAChRα9 and nAChRα10) where it acts as a receptor antagonist. Nicotine is found in the leaves of "Nicotiana rustica", in amounts of 2–14%; in the tobacco plant, "Nicotiana tabacum"; in "Duboisia hopwoodii"; and in "Asclepias syriaca".
