Natural phenols are a class of molecules found in abundance in plants. Many common foods contain rich sources of polyphenols which have antioxidant properties only in test tube studies. As interpreted by the Linus Pauling Institute, dietary polyphenols have little or no direct antioxidant food value following digestion. [7]
Uric acid displays lactam–lactim tautomerism. [4] Uric acid crystallizes in the lactam form, [5] with computational chemistry also indicating that tautomer to be the most stable. [6] Uric acid is a diprotic acid with pK a1 = 5.4 and pK a2 = 10.3. [7] At physiological pH, urate predominates in solution. [medical citation needed]
Uric acid has the highest concentration of any blood antioxidant [58] and provides over half of the total antioxidant capacity of human serum. [64] Uric acid's antioxidant activities are also complex, given that it does not react with some oxidants, such as superoxide, but does act against peroxynitrite, [65] peroxides, and hypochlorous acid.

Uricosurics are often used in the treatment of gout, a disease in which uric acid crystals form deposits in the joints. By decreasing plasma uric acid levels, help dissolve these crystals, while limiting the formation of new ones. However, the increased uric acid levels in urine can contribute to kidney stones.
Hyperuricaemia or hyperuricemia is an abnormally high level of uric acid in the blood.In the pH conditions of body fluid, uric acid exists largely as urate, the ion form. [1] [2] Serum uric acid concentrations greater than 6 mg/dL for females, 7 mg/dL for males, and 5.5 mg/dL for youth (under 18 years old) are defined as hyperuricemia. [3]

Allopurinol is used to reduce urate formation in conditions where urate deposition has already occurred or is predictable. The specific diseases and conditions where it is used include gouty arthritis, skin tophi, kidney stones, idiopathic gout; uric acid lithiasis; acute uric acid nephropathy; neoplastic disease and myeloproliferative disease with high cell turnover rates, in which high urate ...
