(A) Carboxymethyl cellulose (CMC) is a polymer composed of 2-glucopyranose residues (cellulose) with hydroxyl groups substituted by carboxymethyl groups. The CMC monomers are connected with β-(1-4)-glycosidic bonds. The structure of CMC sodium salt is shown. (B) Chitosan polymers consisting of N-acetyl-D-glucosamine and β-(1,4)-linked d-glucosamine. (C) Alginate sodium salt polymers containing 1-4 linked β-D-mannuronic acid and α-L-glucuronic acid residues.
