Acetylcholinease Acetylcholinease, also known as acetylcholinesterase, exists in the brain, nerve cells and muscles in a free state. It is an important substance of the nervous system and can maintain the normal function of the nervous system. It is an important hydrolase that can efficiently hydrolyze the neurotransmitter acetylcholine and maintain the normal progress of nerve impulses. Acetylcholinease is derived from animal tissues and snake venom. It acts on various acetates and can also catalyze acetylation reactions. Organophosphates, carbamates, quaternary ammonium ions and some sulfonated methane have inhibitory effects on Ache's activity. Analytical methods: The classic methods for measuring acetylcholinease by manometry and pH are: measuring the acid produced by acetylcholine during the hydrolysis process; either by measuring the pressure by releasing CO2 or by potentiometric titration. In the manometry method, the amount of hydrolyzed acetylcholine can be directly measured by the Wobble meter. In the potentiometric method, a constant pH titration method or a common pH meter with an external electrode can be used to detect the amount of acid generated. In the constant pH titration method, record the amount of alkali required to maintain a constant pH. The speed of the added alkali is the enzyme speed, which is the measurement of the enzyme-catalyzed hydrolysis rate.
