Uric acid (2,6,8-Trihydroxypurine) - not to be confused with urea - is a nitrogen-containing metabolic product in many animal species and also in humans, which is formed during the breakdown of the purine bases of the nucleic acids. The salts of uric acid are called urates.

About 75% of uric acid is excreted via the kidneys, the rest via saliva, sweat and intestinal secretion.
