Sports Science and Medicine: acetylcholinesterase
Top

An enzyme that breaks down acetylcholine (ACh) into choline and acetic acid. Acetylcholinesterase is released onto the sarcolemma of muscle fibres and destroys ACh after the ACh has combined with receptors on the muscle fibre. Thus, acetylcholinesterase prevents continued muscle contraction in the absence of additional nervous stimulation.
