Figure 12.

Example of structures detected in SEC fractions, the modified RE are highlighted in the boxes: HS sequences are displayed in the upper panel with the terminal T1 at the RE and with the uronic acid or the glucosamine at the non reducing end (NRE) in even or odd oligomers, respectively. CS/DS structures are shown in the lower panel (the substitution pattern of DS is used as example because it is more abundant than CS): two possibly reducing ends are T1 and Ra, the galactosamine is placed at the NRE.
