Glucuronic acid (from Greek γλεῦκος "sweet wine, must" and οὖρον "urine") is a uronic acid that was first isolated from urine (hence the name "uronic acid"). It is found in many gums such as gum arabic (approx. 18%), xanthan, and kombucha tea and is important for the metabolism of microorganisms, plants and animals.
