Web2098-2 Cholinesterase [Enzymatic activity/volume] in Serum or Plasma Active Part Descriptions. LP14299-9 Cholinesterase In biochemistry, cholinesterase is a family of enzymes that catalyze the hydrolysis of the neurotransmitter acetylcholine into choline and acetic acid, a reaction necessary to allow a cholinergic neuron to return to its resting … Cholinesterase inhibitors (ChEIs), also known as anti-cholinesterase, are chemicals that prevent the breakdown of the neurotransmitter acetylcholine or butyrylcholine. This increases the amount of the acetylcholine or butyrylcholine in the synaptic cleft that can bind to muscarinic receptors, nicotinic receptors and others. This group of inhibitors is divided into two subgroups, acetylcholinester…

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 Several of these serve as neurotransmitters. Thus, it is either of two enzymes that catalyze the hydrolysis of these cholinergic … See more The two types of cholinesterase are acetylcholinesterase (ACHE) and butyrylcholinesterase (BCHE). The difference between the two types has to do with their respective preferences for substrates: … See more In 1968, Walo Leuzinger et al. successfully purified and crystallized acetylcholinesterase from electric eels at Columbia University, New York.
