Kinetics of carboxylesterase: An experiment for biochemistry and physical chemistry laboratory

“…For example, methanol reacts with the acyl enzyme to form methyl esters. Also esters of other than carboxylic acids can also serve as substrates except that phosphate esters generate intermediates in reaction (2) which are hydrolyzed so slowly in reaction (3) that the enzyme is effectively tied up as the intermediate and can no longer function. A similar sequence for the related enzyme acetylcholinesterase (9), which is essential in neural transmission, explains the effect of certain organophosphorous esters as nerve gases and insecticides.…”
