Fucoidan is a group of marine sulfated polysaccharides of the cell-wall matrix of brown algae, containing large proportion of L-fucose and sulfate, together with minor amounts of other sugar like xylose, galactose, glucose, mannose, uronic acid, and rhamnose. Fucoidan medically used as anti-inflammatory, antiviral, anticoagulant, antitumor and antiangiogenesis. Fucoidan  changes the  liquid form of blood into gel type leads to blood clotting.
