Common NameGalacturonic acid
DescriptionGalactopyranuronic acid is the pyranose form of D-galacturonic acid. It is a conjugate acid of a D-galactopyranuronate. Galacturonic acid is a sugar acid, an oxidized form of d-galactose. It is the main component of pectin, in which it exists as the polymer polygalacturonic acid. In its open form, it has an aldehyde group at C1 and a carboxylic acid group at C6. Other oxidized forms of d-galactose are d-galactonic acid (carboxylic group at C1) and meso-galactaric acid (mucic acid) (carboxylic groups at C1 and C6). It is also a uronic acid or hexuronic acid. Naturally occurring uronic acids are d-glucuronic acid, d-galacturonic acid, l-iduronic acid and d-mannuronic acid. Galacturonic acid, also known as D-galacturonate or sodium pectate, 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. Galacturonic acid exists in all living species, ranging from bacteria to humans. Galacturonic acid has been found in flaxseeds. Galacturonic acid has also been detected, but not quantified in several different foods, such as common grapes, cocoa beans, roselles, cow milk, and figs.
