Acide glucuronique

Glucuronic acid (from Greek γλεῦκος "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 ( () 18%), xanthan, and kombucha tea and is important for the metabolism of microorganisms, plants and animals. Glucuronic acid is a sugar acid derived from glucose, with its sixth carbon atom oxidized to a carboxylic acid. In living beings, this primary oxidation occurs with UDP-α-D-glucose (UDPG), not with the free sugar. Glucuronic acid, like its precursor glucose, can exist as a linear (carboxo-)aldohexose (
