[ Introduction ]
Xanthine oxidase (XO) is an important molybdenum-containing enzyme involved in purine metabolism. It catalyzes the oxidation of hypoxanthine to xanthine, and further from xanthine to uric acid, producing reactive oxygen species during the reaction process.

[ Uses ]
Xanthine oxidase is an iron-molybdenum flavoprotein enzyme that catalyzes the oxidation of hypoxanthine to xanthine and xanthine to uric acid in purine metabolism. It plays an important role in biochemical research and clinical studies, particularly in relation to gout and oxidative stress.
