The polysaccharide was named as “fucoidin” when it was first isolated from marine brown algae by Kylin in 1913. but some also called it fucan, fucosan or sulfated fucan. Now it is named as “fucoidan” according to IUPAC rules. Fucoidans are sulfated polysaccharides extracted from marine brown seaweed. (Matou et al., 2022) Fucoidan is major posing of fucose, uronic acid, galactose, xylose and sulphated fucose. (Marais and Joseleau, 2022) The chemical positions of most fucoidans are plex. The structures of fucoidans from different brown algae vary from species to species. (Li et al., 2022) Fucoidan contains a substantial percentage of Lfucose and sulfate ester groups, and
