Acetylthiocholine chloride is an AChE (acetylcholinesterase) substrate and AChR (nicotinic acetylcholine receptor) agonist. Acetylthiocholine chloride is a compound used in biochemical assays to measure cholinesterase activity. It serves as a substrate that is hydrolyzed by cholinesterase enzymes, producing thiocholine. Thiocholine then reacts with a chromogenic reagent to generate a colored product, allowing for spectrophotometric measurement.
