Acetylcholine is essential to neural function. It synthesis is catalyzed by choline acetyltransferase, the enzyme responsible for the acetylation of choline by acetyl coenzye A, a reaction favored slightly thermodymodynamically and not at all kinetically. An analytically pure enzyme still has not been obtained; however, method of purification have been

Biosensors for choline, choline esters and inhibitors of choline esterase
Sensors and Actuators B: Chemical, 1991Abstract A choline electrode has been developed by coupling immobilized choline oxidase to a hydrogen peroxide electrode. The co-immobilization of cholinesterase permits acetylcholine to be measured. The excess of both enzymes results in a diffusion-limited electrode response for both substrates, with relative sensitivities 1: 0.6 for choline ...

Choline has many physiological functions throughout the body that are dependent on its available local supply. However, since choline is a charged hydrophilic cation, transport mechanisms are required for it to cross biological membranes. Choline transport is required for cellular membrane construction and is the rate-limiting step for acetylcholine ...
