Why are polysaccharides important?

Together with other biomolecules like proteins and nucleotides, polysaccharides are an essential component and exert many activities in the biological system such as cell–cell communication, adhesion, and molecular recognition in the immune system [ 2 ].

Which polysaccharides can be classified based on a polyelectrolyte?

Polysaccharides can also be classified based on polyelectrolyte to positively charged polysaccharides (chitosan) and negatively charged polysaccharides (alginate, heparin, hyaluronic acid, and pectin [ 5 ].

What are some natural polysaccharides?

Other naturally occurring polysaccharides include pectin, guar gum, amylose, inulin, dextran, chitosan, and chondroitin sulphate, which have been investigated for colon-specific drug release and their ability to be used as pharmaceutical excipients [ 65 ].
