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. The compound features an imidazolone ring. [1]

Contents

Occurrence

It arises via the action of urocanase on urocanic acid. Hydrolysis of the heterocycle to the glutamic acid derivative is catalyzed by imidazolonepropionate hydrolase.

Microbial production of imidazol-4-one-5-propionic acid in the human gut has been shown to affect insulin signaling, which is relevant to type II diabetes. [2]

Imidazole propionate has been causally implicated in atherosclerosis and Parkinson’s disease, primarily by triggering inflammation. Streptococcus mutans, known for its role in dental caries, has been identified as a contributor to elevated ImP levels through the urdA gene, which is involved in the conversion of urocanate to ImP. [3] [4]
