Figure 1.
Monosaccharide composition of the crude polysaccharide fraction (CPS), the unbound fraction (UNBOUND), and the bound fraction (BOUND), following anion exchange purification. Percentages of total monosaccharide content are shown (±SE, n = 4 for CPS and 6 for unbound and bound). The BOUND fraction was enriched in galacturonic acid and contained galactose, arabinose, and rhamnose. The BOUND sample had reduced amounts of glucose, galactose, xylose, and mannose compared to the CPS, which indicated the removal of neutral polysaccharides by the ion exchange procedure.
