1.1.3. Fucoidans
Fucoidan is a fucose-rich sulfated sugar present in the cell wall of a huge number of seaweed including Fucus vesiculosus, Sargassum stenophyllum, Fucus distichus, Hizikia fusiforme, Padina gymnospors, Analipus japonicas, chorda filum, Caulerpa recemosa, andKjellmaniella crassifolia . Fucoidan has varied monosaccharides including xylose, galactose, mannose and glucuronic acid. Fucoidan structure and activity vary with geographical area and seaweed source. It has several combined applications documented with nanoparticles, hydrogels, microspheres, drug-releasing systems, nanofibers, scaffolds and microsphere for tissue design and wound dressing (Venkatesan et al., 2019).
