Displaying 1 results of Acetylloline Stable Isotopes Acetylcholine is a neurotransmitter responsible for many important functions in the body including muscle contraction, cognitive function, and memory formation. To study these functions, researchers use acetylcholine stable isotopes which are non-radioactive forms of the molecule. These isotopes allow for precise tracking of acetylcholine in the body and can provide valuable insight into its role in various physiological processes.
