Uric acid is a heterocyclic compound of carbon, nitrogen, oxygen, and hydrogen with the formula C5H4N4O3. It forms ions and salts known as urates and acid urates such as ammonium acid urate. Uric acid is a product of the metabolic breakdown of purine nucleotides. High blood concentrations of uric acid can lead to gout. The chemical is associated w...

the end product of purine metabolism or oxidation in the body. It is present in blood in a concentration of about 5 mg/100 mL and is excreted in the urine in amounts of a little less than 1 g per day.

Uric acid is a crystalline substance found normally in small quantities in urine in combination with sodium, potassium, and ammonium as urates. It is present in larger quantity in various diseases, particularly gout. Uric acid is formed from the breaking down of muscular tissue and organs, and in the process of digestion.
