Imidazol-4-one-5-propionic acid is an intermediate in the metabolism of histidine. It is a colorless compound that is sensitive to light in air. It arises via the action of urocanase on urocanic acid. Hydrolysis of the heterocycle to the glutamic acid derivative is catalyzed by imidazolonepropionate hydrolase.
