Published: August 2007

Kinetics and mechanism of in vitro hydrolyses of acetylcholine and acetylthiocholine by carbamates were studied in a batch reactor at 25 degrees C, pH 8, and ionic strength of 0.11 M. Every hydrolysis was monitored by 3-4 independent methods. All studied hydrolyses can be described by the model of competitive inhibition with an irreversible step (k3). A table of obtained average values of rate constants and discussion of the resultes are given.
