Metabolite Identification
Common NameIduronic acid
DescriptionIduronic acid, also known as iduronate or acid, iduronic, belongs to the class of organic compounds known as glucuronic acid derivatives. Glucuronic acid derivatives are compounds containing a glucuronic acid moiety (or a derivative), which consists of a glucose moiety with the C6 carbon oxidized to a carboxylic acid. Iduronic acid is an extremely weak basic (essentially neutral) compound (based on its pKa).
