What does xanthine oxidase do?

Xanthine oxidase is a form of xanthine oxidoreductase, an enzyme that generates reactive oxygen species such as superoxide radicals and hydrogen peroxide when it catalyzes the oxidation of hypoxanthine to xanthine, and can further catalyze the oxidation of xanthine to uric acid.

Is xanthine a purine?

1.1. Xanthine is a type of purine, and xanthinuria is a genetic deficiency of xanthine oxidase, a defect in purine metabolism. Xanthine stones (purine stones) are seen in patients with severe hyperuricemia taking allopurinol, or in those with rare inherited forms of xanthinuria.

Is caffeine an alkaloid?

Caffeine is the most common purine alkaloid, but in a few plant species including cacao and unique Chinese tea plants, the main purine alkaloid is theobromine or methyluric acid (Ashihara and Crozier, 1999; Ashihara and Suzuki, 2004). A large amount of caffeine is found in coffee seeds (mainly in endosperms).
