Water-soluble linear sulfated galactans from red seaweeds. They consist of repeating disaccharide units with alternating 3-linked β−d-galactopyranose and 4-linked α-galactopyranose or 3, 6-anhydro- α-galactopyranose. Between the units are α-1,3 glycosidic bonds. kappa, iota, and lambda carrageenan are three main types based on the number of sulfate groups on the repeating disaccharide units.
