Acetylcholine (ACh, pron. ah-Seh-til-KO-leen) is an organic molecule that acts as a neurotransmitter in many organisms, including humans. It is an ester of acetic acid and choline, with chemical formula {chem|link=acetyl|CH|3|CO}O({chem|link=methylene bridge|CH|2})2{chem|link=Nitrogen|N|+}({chem|link=methyl|CH|3})3 and systematic name 2-acetoxy-`....

A chemical made by some types of nerve cells. It is used to send messages to other cells, including other nerve cells, muscle cells, and gland cells. It is released from the nerve ending and carries signals to cells on the other side of a synapse (space between nerve cells and other cells). Acetylcholine helps control memory and the action of certa...

Acetyl ester of choline. Perhaps the best characterized neurotransmitter, particularly at neuromuscular junctions. ACh can be either excitatory or inhibitory, and its receptors are classified as nicotinic or muscarinic, according to their pharmacology. In chemical synapses ACh is rapidly broken down by acetylcholine esterases, thereby ensuring the transience of the signal.
