What Is Serum Uric Acid? Biochemstry, Sources, andRegulation

Purine Metabolism andUric Acid Production

Uric acid is te final product of purine nurotyode katabolism in humans. Purine are nitrogenous bases derived frem two sources: dietary intake (red meat, organ meats, seafood, and beer) and endogenous cellular turnover from DNA andRNA degradatione. The enzyme xanthine oksydase catalyzes thee rate- limiting final steps: hypoxanthine to xanthine and xanthine tine tuc acid. In mot mammals, uricase furicase devic.

Uric Acid and d Oxidative Stress: The Paradox

Paradoxically, uric acid exuts both antioksydant andd pro- oksydant proxicant properties.
