Water-soluble chitin was prepared by a controlled partial N-acetylation of high deacetylation chitosan under homogeneous conditions.

A type of polysaccharide/polypeptide hydride material, chitin derivatives having polypeptide side chains, was prepared by the graft copolymerization of l -leucine N-carboxy anhydride (NCA) onto water-soluble chitin in water/ethyl acetate.

In this paper, a new technics of preparing nonderived, low degree of deacetylation, water-soluble chitin and an assay to define the molecular weight and degree of deacetylation have been investigated.

Study on in vitro antibacterial activity of water-soluble chitosan;
