Ulvan from Ulva ohnoi macroalgae : Green extraction method and physicochemical characterization of the ulvan

Abstract Ulvan belongs to the class of sulfated heteropolysaccharide and is the main component of the seaweed Ulva ohnoi (U. ohnoi). Ulvan has a chemical structure similar to fucoidan, chondroitin sulfate, and hyaluronic acid, which are commonly used to develop drug delivery systems.
