F2 polysaccharide included 3,4,6-Me3-Manp and small amounts of 2,4,6-Me3-Manp, implying that the backbone was also connected through 1,2 or 1,3-glycosidic linkages. Furthermore, the presence of 1,2,3-linked rhamnose and 1,2,4-linked mannose residues (4,6-Me2-Rha and 3,6-Me2-Man, respectively) indicates that some branches may exist at the backbone. |
