Seaweeds are abundant in cell wall polysaccharides, which play an important role in the different fields of industries because of their physiochemical and biofunctional properties. Cladosiphon okamuranus, Okinawa mozuku in Japanese, is utilized edible brown algae in Japan and species in Ryukyu archipelago. Cladosiphon okamuranus possesses the highest content of fucoidan among any brown algal species. Fucoidan is a sulfated polysaccharide consisting of fucose in the main chain substituted by glucuronic acid and exists as a matrix polysaccharide in the cell wall. Fucoidan have been extensively explored for numerous therapeutic effects and bioactivities; consequently, C. okamuranus plays a key role in the fields of pharmaceutical, nutraceutical cosmeceutical, and functional food. However, fucoidan in these studies were mostly extracted with HCl or water and analyzed as an individual polymer. Therefore, we analyzed the whole cell wall of C. okamuranus with the structural differences in predominant polysaccharide types. Here, the cell wall polysaccharide of seaweeds particularly fucoidan is described, focusing on our results of cell wall studies of C. okamuranus.
