Quick Reference

An enzyme that hydrolyses acetylcholine to acetic acid and choline. By destroying acetylcholine after its release from the terminal boutons of presynaptic neurons and from postsynaptic receptors after a nerve impulse has been triggered, it stops further postsynaptic nerve impulses. Also called cholinesterase. See also nerve gas, physostigmine. AChE abbrev. [From acetylcholine + ester + -ase denoting an enzyme, from Greek diastasis separation]
