¹H chemical shifts (δ) of anomeric protons in the deacetylated and sonicated glucuronoxylomannan (GXM) isolated from H99 and JP02 (recorded in D₂O at 70°C).

GXM	ManA	ManB	ManC	GlcA	Xyl1	Xyl2	Xyl3
H99	5.25	5.32	5.18	4.47	4.50	4.40	–
JP02	5.21	5.33	5.14	4.47	4.50	4.29	4.42

The nomenclature of sugar residues is displayed in the predicted structures of GXMs shown in Figure 7. H99 GXM had one more anomeric proton detected at 5.14 ppm (Figure 6Ac). It was also detected in the GXM of the other serotype A strain, but was not assigned previously (Sheng and Cherniak, 1997).
