Urocanic Acid Properties

Urocanic Acid

Molecule Structure Image



Urocanic acid is an intermediate in the catabolism of L-histidine. It was first isolated in 1874 by the chemist M. Jaffé from the urine of a dog. Inherited deficiency of urocanase leads to elevated levels of urocanic acid in the urine, a condition known as urocanic aciduria.
