Butyrylcholine belongs to the class of organic compounds known as acyl cholines. These are acylated derivatives of choline. Butyrylcholine is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Butyrylcholine is a synthetic compound and does not occur in the body naturally. It is used as a tool to distinguish between acetyl- and butyrylcholinesterase. Butyrylcholine is an acetylcholine-like molecule, with activation of some of the same receptors as acetylcholine. It is hydrolyzed by acetylcholinesterase and butyrylcholinesterase (also known as pseudocholinesterase), with butyrylcholinesterase being more efficient than acetylcholinesterase. Butyrylcholine is a nicotinic receptor agonist and mimics the action of acetylcholine (ACh) at both enteric and epithelial nicotinic acetylcholine receptors (nAChRs). Additionally, butyrylcholine is also able to stimulate muscarinic acetylcholine receptors (mAChRs) (PMID: 6481626, 27423041).
