L-Triguluronic acid（Cat No.:I044867）is a trisaccharide composed of three L-guluronic acid units linked via 1→4 glycosidic bonds. It is a structural component of alginate, a polysaccharide derived from brown seaweed, and plays a crucial role in the formation of alginate gels through interactions with divalent cations like calcium. Due to its rigid, buckled conformation, L-Triguluronic acid exhibits strong binding affinity for metal ions, contributing to the stiffness and stability of alginate networks. It is valuable in biomaterials research, particularly in drug delivery, tissue engineering, and the design of ion-sensitive hydrogels.
