Fucan / Galactofucan
Fucans are acid polysaccharides occurring in brown marine seaweeds cell wall (Phaeophyceae, mainly Fucales and Laminariales), in sea urchin egg gelatinous coat, and in sea cucumber cuticule.
Numerous variations of the basic structure are found in different species of Phaeophycea. The structure of fucan polysaccharide consists of α-(1-3) linked L-fucose sulphates backbone in some order (eg Laminariales) with alternating α-(1-3) and α-(1-4) linked residues in other orders (eg Fucales). Other units (like galactose) and substitutions (acetate) also occur.
Galactofucan is a fucan polysaccharide containing sulphated D-galactose. Galactofucan is extracted from the brown seaweed Undaria pinnatifida.

POTENTIAL ACTIVITIES
Fucans and galactofucan exhibit numerous potential therapeutic activities. In particular, they have been shown to have anticoagulant/heparin-like activities, antiviral and antiparasitic activities. They can act has antiangiogenic and antitumoral agents.
