Acetylcholine is the first recognized and best-studied of the neurotransmitters. At receptors it is recycled 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. [ WordNet 1.5 +PJC ] | | acetylcholinesterase | n. 1. an enzyme which exists in nerve cells and hydrolyses acetylcholine into choline and acetic acid.
