Acetylthiocholine iodide CAS:1866-15-5
Acetylthiocholine iodide is a chemical compound that is commonly used as a substrate in enzyme assays to measure the activity of the enzyme acetylcholinesterase (AChE). AChE is an enzyme that hydrolyzes the neurotransmitter acetylcholine, a critical step in terminating the signal transmission between nerve cells.
When acetylthiocholine iodide is acted upon by AChE, the acetyl group is removed, resulting in the formation of thiocholine and acetate ions. Thiocholine then reacts with a colorless reagent called DTNB (5,5′-dithiobis(2-nitrobenzoic acid)) to produce a yellow-colored compound called 5-thio-2-nitrobenzoate, which can be measured spectrophotometrically. The rate of color development is directly proportional to the activity of AChE in the sample.
