Potentiometric choline electrodes were developed on the basis of the mediator-free bioelectrocatalysis. The electrodes made of a composite carbon-polymer material contain choline oxidase and peroxidase coimmobilized on the surface of the electrode. The rate of the potential increase was shown

Acetylcholine levels of whole blood from 80 healthy subjects were determined by pyrolysis-gas chromatography-mass fragmentography. Acetylcholine was extracted from 1.2 ml of venous blood in the presence of eserine, demethylated by pyrolysis, and assayed by selected ion-current monitoring using butyrylcholine

The hydrolysis of long-chain alkanoylcholines catalyzed by butyrylcholinesterase (EC 3.1.1.8) has been studied. Radiolabelled substrates have been used and a radiochromatographic detection method developed earlier has been applied. The long-chain choline esters were found to be excellent substrates for butyrylcholinesterase

The dibucaine number (DN) was determined for serum cholinesterase (EC 3.1.1.8, SChE) in plasma samples. The ones with a DN of 79-82 were used, because they had the "usual" SChE variant. The enzyme was assayed colorimetrically by the reaction of

Acetylcholinesterases from Drosophila melanogaster and Torpedo marmorata possess 35% identical residues. We built a homology model of the Drosophila enzyme on the basis of the known three-dimensional structure of Torpedo acetylcholinesterase, which revealed an oval rim of the active site
