Kinetics and mechanism ofin vitrohydrolyses of ace- tylcholine and acetylthiocholine by carbamates were studied in a batch reactor at 25∞C, pH 8, and ionic strength of 0.11m. Every hydrolysis was monitored by 3Ð4 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.

Key words:Acetylcholine, Hydrolysis, Kinetics, Cholin- esterases
