Advances in Phosphorylation, Structure Characterization, and Biological Activities of Polysaccharides

Abstract:

The biological activities of natural polysaccharides are often limited by their structures, which make it difficult to meet practical application requirements. Phosphorylation is an important chemical modification method, and the unique chemical structures can significantly enhance the antioxidant, immunomodulatory, and antitumor activities of phosphorylated polysaccharides. In recent years, this field has attracted widespread attention. To verify the success of phosphorylation and determine the degree and location of phosphorylation, various methods can be used to characterize the structures of phosphorylated polysaccharides. The author summarizes the latest research findings on phosphorylated polysaccharides and particularly focuses on their production methods, structural characterization, and biological activities, aiming to provide a theoretical foundation and practical recommendations for their application in food, pharmaceuticals, and related fields.
