It binds with two distinct classes of receptors - one that comes in five types that are coupled to G proteins, and another class of ionotropic receptors.  
The serine protease that normally breaks down this compound can be permanently inactivated by di-isopropyl-phospho-fluoridate, or temporarily inhibited by neostigmine, which is used as a treatment for myasthenia gravis because it prolongs the actions of this compound.  It binds with two distinct classes of receptors - one that comes in five types that are coupled to G proteins, and another class of ionotropic receptors.  Those muscarinic receptors for this molecule are found at effector organs of the parasympathetic nervous system, while nicotinic receptors for it are found at all autonomic ganglia and at motor end plates of skeletal muscles.  Broken down by a namesake esterase, FTP name this neurotransmitter synthesized from its two namesake constituents, one of which includes coenzyme A.
