Unit Definition

One unit will oxidize 1.0 μmole of glycerol to dihydroxyacetone per min at 25 °C at pH 10.0.

Physical form

Lyophilized powder containing bovine serum albumin


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.

Biochem/physiol Actions

Glycerol dehydrogenase catalyzes the conversion of glycerol to glycerone.

Physical properties

Isoelectric point : 4.4 ± 0.1
Michaelis constants : 1.1 x 10¯2M (Glycerol), 8.9 x 10¯5M (NAD+)
Structure : 10 subunits (42,000) per mol of enzyme
Inhibitors : p-Chloromercuribenzoate, o-phenanthroline, monoiodoacetate, heavy metal
ions (Co++, Ni++, Cu++, Zn++, Cd++)
Optimum pH : 10.0 – 10.5
Optimum temperature : 50°C
pH Stability : pH 7.5 – 10.5 (25°C, 20hr)
Thermal stability : below 55°C (pH 7.5, 15min)
Substrate specificity : This enzyme has the highest specificity for glycerol and 1,2-propanediol, and also oxidizes glycerol-α-monochlorohydrin, ethylene
glycol and 2,3-butanediol. The oxidative reaction is stimulated by K+, NH+4 and Rb+.
