Description and Uses

Uric Acid is a heterocyclcic compound that is created when purine nucleotides are broken down of by the human body. High blood concetration of Uric Acid is known as hyperuricemia and is often associated with a wide range of disorders and medical conditions such as gout, diabetes and metabolic syndrome. Uric acid may be a marker of oxidative stress and may have a potential therapeutic role as an antioxidant.

• Toxicity: A nitrogenous end product and the principal excretory product of purine metabolism in mammals. In birds and reptiles, it is the principal end product of nitrogen metabolism in general. Defects in uric acid metabolism and excretion appear to be associated with a number of disease states, and it frequently occurs as a component of renal calculi. It has not been associated closely with toxic insults except in the case of lead poisoning. Lead causes an elevation in blood uric acid concentration (uric acidemia) and a decrease in uric acid excretion.
