'''Acetylcholine''' is an organic cation that acts as a [[neurotransmitter]] in many organisms, including humans.

Acetylcholine is also the principal neurotransmitter in all autonomic ganglia.

==Chemistry==

It is an ester of acetic acid and [[choline]]. The molecule is a polyatomic cation, meaning that it is a positive ion comprising of more than one atom.

It is an ester of acetic acid and [[choline]]. The molecule is a polyatomic cation, meaning that it is a positive ion comprising of more than one atom. Acetylcholine is a quaternary ammounium cation.

====[[Antagonists]]====

An acetylcholine receptor [[antagonist]] works by attaching to acetylcholine receptors to prevent agonists binding. The [[deliriant]] drugs [[atropine]], [[scopolamine]] and [[diphenhydramine]] all act as antagonists upon muscarinic acetylcholine receptors, as does the chemical incapacitating agent 3-Quinuclidinyl benzilate, better known as BZ.

An acetylcholine receptor [[antagonist]] works by attaching to acetylcholine receptors to prevent agonists binding. The [[deliriant]] drugs [[atropine]], [[scopolamine]] (both found in Datura) and [[diphenhydramine]] all act as antagonists upon muscarinic acetylcholine receptors, as does the chemical incapacitating agent 3-Quinuclidinyl benzilate, better known as BZ.
