Digalacturonic acid (CAS 5894-59-7)

Digalacturonic acid, a polysaccharide formed by linking two galacturonic acid molecules through a glycosidic bond, occurs naturally in the cell walls of numerous plants and algae. Resembling the structure of cellulose, Digalacturonic acid often serves as an alternative to cellulose in various applications. In scientific research, Digalacturonic acid has undergone extensive investigation, uncovering its manifold benefits. It has been employed in the production of enzymes such as pectinase and xylanase, which aid in breaking down plant cell walls. Furthermore, Digalacturonic acid has been instrumental in the synthesis of polysaccharides like cellulose, enabling the creation of biodegradable materials. Additionally, It is used to study the transport of oligogalacturonides by systems such as the TogMNAB ABC transporter. Although the precise mechanism of action of Digalacturonic acid remains incompletely understood, it is believed to stem from its ability to bind with proteins, lipids, and carbohydrates. The highly branched structure of Digalacturonic acid facilitates interactions through multiple hydrogen bonds with other molecules.
