Chitin hydrogel
WebChitin from shrimp shells is suitable for analysis of chitinase. It is a polysaccharide composed of N-acetyl-D-glucomasine that can also be used for the manufacture of glucosamine and chitosan. Chitin from shrimp shells, a long-chain polymer of a β-1,4 linked N-acetylglucosamine residues, may be used to study its physicochemical … WebHydrogel has been known as an ideal cartilage regeneration scaffold. However, to date, in vitro cartilage regeneration based on hydrogel has not achieved satisfactory results. The current study explored the feasibility of in vitro 3D cartilage regeneration based on a moldable thermosensitive hydroxypropyl chitin (HPCH) hydrogel and its in vivo ...
