Chemical representations of the model sulfated fucan-derived octasaccharides from (A and B) IbSF, and (C and D) HfSF. (B) Octasaccharide IbSF II has 2-desulfation at Dr relative to (A) IbSF I. Similarly, (D) HfSF II is 2-desulfated at Anr compared to (C) HfSF I. Pairs of sulfate groups (SO3−) and hydroxyl (OH) groups involved in hydrogen bonds are shown with the same colors. Those not forming any hydrogen bond are colored in black. Intra-residue hydrogen bonds between sulfate (SO3−) and hydroxyl (OH) groups in the terminal residues (Dnr or Ar) are shown in gray.
