Examples of AChEIs Venoms, poisons, nerve agents, organophosphate pesticides, tetrahydrocannibol (THC), carbamates (including physostigmine, neostigmine, pyridostigmine). The classical role of ACHE is to terminate cholinergic neurotransmission by hydrolysis of acetylcholine (ACH). Acetylcholinesterase/ACHE: Products. Acetylcholinesterase is secreted by the muscle and remains attached to it by collagen fastened to the basal lamina. Die Pseudocholinesterase (auch Butyrylcholinesterase, BuChE) ist ein Enzym, das die hydrolytische Spaltung der Esterbindung in Cholinestern katalysiert. Acetylcholinesterase, also nomenclated as AChE is an enzyme found in the red blood cells which catalyzes the breakdown of choline esters that primarily function as neurotransmitters. Anticholinesterase, any of several drugs that prevent destruction of the neurotransmitter acetylcholine by the enzyme acetylcholinesterase within the nervous system. Operationally, there are two strategies to determine/assess resistance to aldicarb. From Proteopedia.
