Galactosylated chitosan(GC)

Galactosylated chitosan is a modified form of chitosan, a polysaccharide derived from the deacetylation of chitin, a natural polymer found in the shells of crustaceans.Galactosylation imparts Galactose receptors targeting properties to chitosan, which can selectively bind to the asialoglycoprotein receptor (ASGPR) found on the surface of hepatocytes in the liver.
