BIOTECHNOLOGICAL SULPHATED CHONDROITIN SULPHATE AT POSITION 4 OR 6 ON THE SAME POLYSACCHARIDE CHAIN, AND PROCESS FOR THE PREPARATION THEREOF

摘要

A method for chondroitin sulphate production provides received unsulphated chondroitin back¬bone chemical sulphation by biothechnological process providing N-acetyl-D-galactosamine unit monosulphation in the same polysaccharide chain at position 4 or 6 close to chondroitin natural sulphation.
