Neuraminic acid linkages

It has been observed that the neuraminic acid linkages can also be conveniently analyzed by the methylation technique.33,34 Some important fragments, the origins of which were confirmed by deuteriumlabelling experiments,33 are shown for two common, N-acetylneura-minic acid derivatives, namely, the terminal sugar derivative 10 and the 8-O-substituted N-acetylneuraminic acid (11). [Pg.401]

Acid-labile linkages of carbohydrates are commonly those of furano-sidic sugar residues or of deoxy monosaccharides.50,63 Consequently, neuraminic acid and fucose residues, which occur as terminal monosaccharides of protein- and lipid-linked glycans, are removed by hydrolysis with a dilute acid. The linkages formed by these two sugar residues can conveniently be differentiated by subjecting a portion of... [Pg.408]

The linkage of neuraminic acid to glycoconjugates is among the most labile glycosidic linkages and can be cleaved in vitro under mildly acidic conditions... [Pg.217]
