Polysaccharides of brown algae

A sulfated peptidoglycuronoglycan, pelvecyan, has been isolated from the brown algaP. wrightii. Its carbohydrate moiety contains D-galactose, D-mannose, D-xylose, L-fucose, and hexuronic acid residues. The polypeptide component consists of 16 amino acids and may be bound to the polysaccharide moiety by ionic bonds.
Pelvecyan is similar in nature and properties to sargassan, which was isolated from the brown algaSargassum pallidum.
