WebThis lesson introduces a biological enzyme called acetylcholinesterase. Our primary points of discussion will center around its definition and how it functions at the cellular level. WebDefinition: Esterase with broad substrate specificity. Contributes to the inactivation of the neurotransmitter acetylcholine. Can degrade neurotoxic organophosphate esters.

WebAcetylcholinesterase Inhibitor. AChE inhibitor (generally referred to as cholinesterase inhibitor) is a chemical that binds to the enzyme, cholinesterase, and prevents it from breaking down the neurotransmitter, ACh. With toxic doses, the result is that excessive levels of the ACh build up in the synapses and neuromuscular junctions and glands. The term cholinesterase is sometimes used to refer specifically to butyrylcholinesterase, but this usage produces the oddity that cholinesterase and false cholinesterase (pseudocholinesterase) under that scheme mean the same thing (confusingly), and acetylcholinesterase is then called true … See more The enzyme cholinesterase (EC 3.1.1.8, choline esterase; systematic name acylcholine acylhydrolase) catalyses the hydrolysis of choline-based esters: an acylcholine + H2O = choline + a carboxylate See more The two types of cholinesterase are acetylcholinesterase (ACHE) and butyrylcholinesterase (BCHE).
