Structural modification and biological activities of carboxymethyl .

Polysaccharides are good chelating agents for metal ions, which are often used to synthesize polysaccharide metal ion complexes. With carboxymethyl (CMP) as the substrate, carboxymethyl iron (CMPF), carboxymethyl selenium (CMPS), and carboxymethyl zinc (CMPZ) were synthesized by response surface methodology, and their biological characteristics were studied. The results showed that the CMP was a β-polysaccharide, and the degree of carboxymethylation was 0.
