A polysaccharide that is α-D-Manp-(1→3)-[β-D-Manp-(1→6)]-β-D-Manp-(1→4)-β-D-GlcpNAc-(1→4)-β-D-GlcpNAc in which a hydroxy group in one of the terminal mannose moieties has been converted into the corresponding Neu5Ac-(1→?)-?-D-Gal-(1→?)-?-D-GlcNAc-(1→?)- glycoside, while two of the hydroxy groups on the other terminal mannose moiety have each been converted into the corresponding Neu5Ac-(1→?)-?-D-Gal-(1→?)-?-D-GlcNAc-(1→?)- glycoside. For the structure shown, either one of the R1 atoms and two of the R2 atoms represent Neu5Ac-(1→?)-?-D-Gal-(1→?)-?-D-GlcNAc-(1→?)- groups or vice versa; the remaining R1 and R2 atoms are hydrogens. |
