Description
Glycerol dehydrogenase is an enzyme in the oxidoreductase family that utilizes the NAD+ to catalyze the oxidation of glycerol to form glycerone (dihydroxyacetone).
Abbr
GDH, Native (Cellulomonas sp.)
Applications
This enzyme is useful for enzymatic determination of glycerol and of triglyceride when coupled with lipoprotein lipase in clinical analysis. Formation of NADH from the reaction of glycerol and NAD+ was catalyzed by the enzyme glycerol dehydrogenase.
