| Main Chain | The main chain of sulfated galactans in the cell wall of red algae is composed of disaccharide repeating segments in which (1→3)- and (1→4)-linked α,β-D (L)-galactose residues alternately form. For example, the main chain of κ-carrageenan is (1→4)-3,6-anhydro-α-D-galactose-(1→3)-β-D-galactose, etc., and the main chain of agarose is (1→4)-3,6-anhydro-α-L-galactose-(1→3)-β-D-galactose, etc. | ||
| Side Chain | Sulfate groups, methyl ethers, and pyruvic acid are often combined with these polysaccharides and replace galactose residues at different positions. For example, in κ-carrageenan, the (1→3)-β-linked Galp unit is sulfated at the O - 2 and/or O - 4 positions, and the (1→4)-α-linked Galp unit is sulfated at the O - 2, O - 3, and/or O - 6 positions. | ||
