Digalacturonic acid

Description:

Digalacturonic acid is a dicarboxylic acid and a structural component of pectin, a polysaccharide found in plant cell walls. It is formed by the partial hydrolysis of pectin and consists of two galacturonic acid units linked by a glycosidic bond. This compound is characterized by its ability to form gels in the presence of calcium ions, making it significant in food technology, particularly in the production of jams and jellies. Digalacturonic acid is soluble in water and exhibits a high degree of polarity due to its carboxylic acid functional groups, which can participate in hydrogen bonding. Its presence in plant materials contributes to the texture and stability of various food products. Additionally, digalacturonic acid has potential applications in pharmaceuticals and biotechnology, as it can influence cell wall properties and has been studied for its role in plant defense mechanisms. Overall, its unique structural features and functional properties make it an important compound in both natural and industrial contexts.

Digalacturonic acid

CAS: 5894-59-7

Digalacturonic acid (DGA) (α-1,4 galacturonobiose), is derived from pectin or pectic acid, by enzymatic or partial acid hydrolysis. It is used in the co-crystallization of enzymes such as proteinase K. It is also used in galacturonic acid metabolism research as a substrate to identify, differentiate, and characterized endo- and exopolygalacturonase(s), and gluconase(s).
