xanthine oxidase

Xanthine oxidase is an enzyme in the body that helps break down substances called purines, which are found in many foods. During this process, it converts purines into uric acid, a waste product that your body needs to eliminate. Sometimes, excessive activity of this enzyme can cause too much uric acid to build up, leading to gout, a painful joint condition. Medications that inhibit xanthine oxidase are used to lower uric acid levels and treat such conditions. Overall, it plays a key role in purine metabolism and maintaining balance in the body's chemical processes.
