Glucuronic acid (from Ancient Greek γλυκός "sweet" + οὖρον "urine") is a carboxylic acid. Its structure is similar to that of glucose. However, glucuronic acid's sixth carbon is oxidized to a carboxylic acid. Its formula is C6H10O7.
The salts and esters of glucuronic acid are known as glucuronates; the anion C6H9O7− is the glucuronate ion.
Glucuronic acid should not be confused with gluconic acid, a linear carboxylic acid resulting from the oxidation of a different carbon of glucose. Both glucuronic acid and gluconic acid are reported to be found in kombucha.
