A peroxidase is one of a number of enzymes that act as catalysts to allow a variety of biological processes to take place. Specifically, they promote the oxidation of various compounds using naturally occurring peroxides, especially hydrogen peroxide (H 2 O 2), which are reduced, forming water.n fact, most of the the people that receive positive results on a thyroid peroxidase test (somewhere between 70 -90%) do indeed have chronic thyroidosis, however there are a some auto-immune disorders that can cause a false positive as well.
1 Xanthine oxidase can also act on certain other purines, pterins, and aldehydes. 2  For example, it efficiently converts 1-methylxanthine (a metabolite of caffeine) to 1-methyluric acid, but has little activity on 3-methylxanthine.anthine oxidase is a superoxide-producing enzyme found normally in serum and the lungs, and its activity is increased during influenza A infection. During severe liver damage, xanthine oxidase is released into the blood, so a blood assay for XO is a way to determine if liver damage has happened.
