| Common Name | 4-Imidazolone-5-propionic acid |
|---|
| Description | 4-Imidazolone-5-propionic acid, also known as 4-imidazolone-5-propanoate, belongs to the class of organic compounds known as imidazolyl carboxylic acids and derivatives. These are organic compounds containing a carboxylic acid chain (of at least 2 carbon atoms) linked to an imidazole ring. An imidazol-4-one having a 2-carboxyethyl substituent at the 5-position. 4-Imidazolone-5-propionic acid is a strong basic compound (based on its pKa). 4-Imidazolone-5-propionic acid exists in all living organisms, ranging from bacteria to humans. Within humans, 4-imidazolone-5-propionic acid participates in a number of enzymatic reactions. In particular, 4-imidazolone-5-propionic acid can be converted into urocanic acid through its interaction with the enzyme urocanate hydratase. In addition, 4-imidazolone-5-propionic acid can be converted into formiminoglutamic acid through the action of the enzyme probable imidazolonepropionase. In humans, 4-imidazolone-5-propionic acid is involved in histidine metabolism. |
