L-Tetraguluronic Acid（Cat No.:I044866）is a linear uronic acid derivative composed of four L-guluronic acid residues linked by 1→4 glycosidic bonds. It occurs naturally as part of the polysaccharide alginate, which is derived from brown algae. L-Tetraguluronic acid is known for its strong gel-forming capacity when cross-linked with divalent cations like calcium, making it useful in biomedical and food applications. Its configuration and stereochemistry contribute to rigidity and ionic binding. In research, it serves as a model for studying alginate behavior and ion-exchange properties in biomaterials and drug delivery systems.
