CAS 51-84-3: Acetylcholine
Description:Acetylcholine is a vital neurotransmitter in both the central and peripheral nervous systems, playing a crucial role in transmitting signals between nerve cells and muscles. It is a quaternary ammonium compound, characterized by its structure, which includes an acetyl group and a choline moiety. Acetylcholine is synthesized from acetyl-CoA and choline through the action of the enzyme choline acetyltransferase. It is involved in various physiological functions, including muscle contraction, modulation of heart rate, and cognitive processes such as memory and learning. Acetylcholine acts on two main types of receptors: nicotinic and muscarinic, which mediate different physiological responses. Its action is terminated by the enzyme acetylcholinesterase, which hydrolyzes acetylcholine into acetate and choline, thus regulating its levels in the synaptic cleft. Due to its critical role in neurotransmission, acetylcholine is also a target for various pharmacological agents, including those used in the treatment of neurological disorders. Its CAS number is 51-84-3, which uniquely identifies this compound in chemical databases.
