n.
An enzyme in the blood and in certain tissues that catalyzes the hydrolysis of acetylcholine.

acetylcholinesterase

(əˈsiːtaɪlˌkəʊliːnˈɛstərˌeɪz; ˈæsɪtaɪl-)
n
(Biochemistry) an enzyme in nerve cells that is responsible for the destruction of acetylcholine and thus for switching off excitation of the nerve

(əˌsit lˌkoʊ ləˈnɛs təˌreɪs, -ˌreɪz, əˌsɛt-, ˌæs ɪ tl-)

Acetylcholine levels are regulated by an enzyme called acetylcholinesterase. An efficient way to boost acetylcholine in the brain is to reduce activity of the enzyme (acetylcholinesterase) that degrades this vital neurotransmitter (acetylcholine).
