Enzymatic Methods of Analysis the methods for the quantitative determination of chemical substances in solution based on the use of enzymes. Enzymatic methods are employed to determine the quantity of substances that are capable of taking part in chemical reactions catalyzed by enzymes, as well as of substances that are activators or inhibitors of enzymes. The methods are characterized by high sensitivity and specificity since enzymes catalyze the conversion of substances with great speed and selectivity. These characteristics hold even when the compound to be analyzed is mixed with other substances similar in chemical structure. In making a determination of the substrate in an enzyme-catalyzed reaction, an enzyme and the other components necessary for the réaction are added to the sample. When the reaction is completed, the quantity of the reaction product in the solution is measured. For example, the determination of ethanol in a solution using the enzyme alcohol dehydrogenase ...
