Catalog #: P2010002 – 250 U

Cholestrerol Oxidase (250 U) consists of a highly purified powdered Cholesterol Oxidase enzyme, a flavoprotein involved in the first step of cholesterol catabolism. The enzyme first oxidizes cholesterol to cholest-5-en-3-one then isomerizes it to cholest-4-en-3-one while producing hydrogen peroxide H2O2. Custom bulk orders of this product are available upon request.

About Cholesterol Oxidase

Cholesterol oxidase belongs to the oxidoreductases enzymatic family. This enzyme specifically acts on the CH-OH functional group. The systematic name of the enzymatic class is cholesterol:oxygen oxidoreductase. This enzyme can be also found under the names of  cholesterol- O2 oxidoreductase, 3beta-hydroxy steroid oxidoreductase, and 3beta-hydroxysteroid:oxygen oxidoreductase. The Cholesterol oxidase enzyme plays important roles in the synthesis of bile acids.
