Acetylcholinesterase (AChE)

Acetylcholinesterase (AChE) is an enzyme in the nervous system that breaks down a chemical called acetylcholine, which transmits signals between nerve cells. When a nerve signal is sent, acetylcholine is released to activate muscles or other nerves. AChE then quickly degrades acetylcholine to stop the signal, ensuring muscles relax and nerves reset for the next message. This regulation is vital for proper nerve function, muscle movement, and cognitive processes. Disruption of AChE activity can lead to abnormal nerve signaling, which is involved in certain diseases and the action of some nerve agents or insecticides.
