Stabilized liquid enzyme and coenzyme compositions and method of preparing same

Abstract From the Canadian patent

Labile coenzymes such as nicotinamide-adenine dinucleotide (NAD), are stabilized by treatment with an organic solvent such, as propylene glycol, in an aqueous media and a suitable polymer which does not inhibit enzymatic activity. An azide compound may be added to the solution, which not only serves as a bacteriostat, but also functions as a stabilizer. In addition a second, coenzyme, such as adenosine triphosphate (ATP) may also be, stabilized in the same solution. Moreover one or more enzymes, such as hexokinase and glucose-6-phosphase dehydrogenase may, be stabilized against denaturation in the same solution. The composition exhibits excellent shelf life and the container, therefor may …
