 Oxyrase® is a biocatalytic oxygen-reducing agent. Oxyrase® removes dissolved oxygen from aqueous, gaseous, and semisolid environments. The oxygen-reducing activity of Oxyrase® starts when Oxyrase® comes in contact with oxygen and a hydrogen donor. Lactic acid, succinic acid, formic acid, alpha-glycerol phosphate, or their salts, are hydrogen donors for Oxyrase®.
These substrates are present in many natural materials at concentrations that insure rapid and complete removal of dissolved oxygen without further additions. However, in some instances by adding more hydrogen donor or combinations of hydrogen donors, the rate of oxygen depletion is faster. Typically 10 mM to 20 mM of substrate is sufficient for Oxyrase® activity in most applications.
The end products of the Oxyrase® reaction are also natural products. The product of the reaction with lactic acid is pyruvic acid; with formic acid it is carbon dioxide and water; with succinic acid it is fumaric acid; and with alpha-glycerol phosphate it is dihydroxyacetone phosphate.
