Description

Application

In the food industry, the primary catalysis is coupled to conversion of NADH and H+ to NAD+ with diaphorase coupled with converting the non-fluorescent resazurin to the highly fluorescent substance resorufin to measure the content of D-lactate in food products.

Biochem/physiol Actions

D-lactic dehydrogenase catalyzes the conversion of D-lactate into D-pyruvate while reducing NAD+ to NADH and H+.

Other Notes

Spectrophotometric assay for D-(-)-lactate in plasma

Unit Definition

1 U corresponds to the amount of enzyme which will reduce 1 μmol of pyruvate to D-lactate per minute at pH 7.0 and 25°C
