Acetylene release at peripheral cholinergic nerve terminals

The phrase "Acetylene release at peripheral cholinergic nerve terminals" appears to be incorrect or based on a misunderstanding. The correct neurotransmitter released at peripheral cholinergic nerve terminals is **acetylcholine**, not acetylene[1][4][6]. Acetylcholine is a well-characterized neurotransmitter involved in transmitting signals across synapses, particularly in the neuromuscular junction and autonomic nervous system[1][4]. It is synthesized from choline and acetyl-CoA by the enzyme choline acetyltransferase, stored in vesicles, and released upon stimulation of the presynaptic terminal[1][3][5]. After its release, acetylcholine acts on muscarinic and nicotinic receptors before being rapidly degraded by acetylcholinesterase[1][4]. There is no known physiological or pharmacological process involving "acetylene" (a simple hydrocarbon gas) as a neurotransmitter or signaling molecule in mammalian biology. Therefore, this entry should be flagged as incorrect for target mapping purposes. The correct canonical form would relate to "Acetylcholine release at peripheral cholinergic nerve terminals," which refers to a biological process rather than a discrete molecular target such as an enzyme or receptor. If you are seeking information about targets involved in this process (e.g., vesicular acetylcholine transporter [VAChT], choline transporter [CHT], muscarinic/nicotinic receptors), those should be specified individually for structured data extraction[2][3].
