(gcide) | acetylcholine \acetylcholine\ n.
1. a neurotransmitter released by the transmitting dendron at

into choline by the action of acetylcholinesterase.
Acetylcholinesterase inhibitors therefore function as
nerve poisons. For biochemical studies it is prepared
typically in the chloride or bromide forms.
