Synthesis of new glycosaminoglycans-like families by regioselective oxidation followed by sulphation of glucoglucuronan from Rhizobium sp. T1

► A new β-(1,3),β-(1,4)-polyglucuronic acid sodium salt from regioselective oxidation of glucoglucuronan from Rhizobium sp. T1. ► A new family of biological glycosaminoglycans like polysaccharide. ► This new over-sulphated β-(1,3),β-(1,4)-polyglucuronic acid sodium salt could act as regenerating agent.
