Study Notes
Uric Acid Structure and Formation
- Uric acid is a heterocyclic compound with the formula C5H4N4O3.
- It is produced from xanthine and hypoxanthine through the action of xanthine oxidase.
- Xanthine and hypoxanthine are derived from purine.
Production Sites
- Uric acid is mainly produced in the liver, kidney, and intestine.
Blood Concentration and Gout
- High blood concentrations of uric acid can lead to gout.
- Normal reference range for uric acid in human blood plasma:
- Male: 237.9～356.9μmol/L (4～7mg/dL)
- Female: 178.4～297.4μmol/L (3～6mg/dL)
- This range is considered normal by the American Association of Medical Physicians.
- Uric acid concentrations above 6mg/dL or below 3mg/dL are considered abnormal.
