UV-method for the determination of L-Lactic Acid in foodstuffs,
beverages and other materials

                     (L-lactate dehydrogenase)
(1) L-Lactic acid + NAD+ ↔ pyruvate + NADH + H+

                   (glutamate-pyruvate transaminase)
(2) Pyruvate + D-glutamate → D-alanine + 2-oxoglutarate
