Cholinesterase an enzyme that hydrolyses and destroys excess acetylcholine after it has been liberated and has produced its effect on specific sites on the postsynaptic membrane at a nerve synapse. An acetylcholinesterase inhibitor often abbreviated achei or anti cholinesterase is a chemical or a drug that inhibits the acetylcholinesterase enzyme from breaking down acetylcholine thereby increasing both the level and duration of action of the neurotransmitter acetylcholine.

Plasma cholinesterase and true cholinesterase are measured during a cholinesterase blood test.
Define cholinesterase. Cholinesterase definition an enzyme found especially in the heart brain and blood that hydrolyzes acetylcholine to acetic acid and choline. In biochemistry a cholinesterase or choline esterase is a family of esterases that lyses choline based esters several of which serve as neurotransmitters. Cholinesterase ko li nes ter ace is one of many important enzymes needed for the proper functioning of the nervous systems of humans other vertebrates and insects.
How to use cholinesterase in a sentence. Thus it is either of two enzymes that catalyze the hydrolysis of these cholinergic neurotransmitters such as breaking acetylcholine into choline and acetic acid. The test helps doctors determine whether or not an individual is poisoned and to what degree by examining the measurement of cholinesterase as a percentage of the individuals blood sample.
Cholinesterase definition is an enzyme that occurs chiefly at neuromuscular junctions and promotes the hydrolysis of acetylcholine at postsynaptic receptors. Cholinesterase an enzyme that hydrolyses acetylcholine into choline and acetic acid enzyme any of several complex proteins that are produced by cells and act as catalysts in specific biochemical reactions. Cholinesterase an enzyme that rapidly breaks down acetylcholine to acetic acid and choline so that its action as a neurotransmitter ceases.
How to use acetylcholinesterase in a sentence. An enzyme that hydrolyses acetylcholine to choline and acetic acid meaning pronunciation translations and examples. Acetylcholinesterase definition is an enzyme that occurs chiefly in cholinergic nerve endings and promotes the hydrolysis of acetylcholine.
