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+.

Packaging

500, 2500 units in poly bottle

Unit Definition

One unit will reduce 1.0 μmole of pyruvate to D-lactate per min at pH 7.0 at 25 °C.

Physical form
