WebAcetylthiocholine iodide (see Section 9) is converted to acetate and thiocholine iodide by the corresponding esterase. Thiocholine iodide and 5,5'-dithio-bis-2-nitrobenzoic acid (DTNB; Ellmanns reagent) react to form the yellow dye-stuff 5-thio-2-nitrobenzoic acid as shown in the following equation: ’ BiomonitoringMethods,Vol. 3 The basis for the thiocholine assays is the hydrolysis of ATCh or related substrates by the enzyme, producing a thiol group that reacts with a sulfhydryl-sensitive chromogen such as dithiobisnitrobenzoate (DTNB). In this case, peak absorption of the thionitrobenzoate produced is at 410–412 nm.
