Structural characterization of the fucosylated XyG oligosaccharides (XXFG and XLFG) from S. peruvianum pollen tubes. (A) MALDI-TOF MS spectrum of permethylated oligosaccharides. Ions are in the [M+Na]+ adduct except for those annotated with + ([M + K]+ adduct). Ions labelled by * correspond to underpermethylated ions. (B) MALDI-TOF/TOF MS of the precursor ion at m/z = 1743·9 ([M + Na]+ adduct) of the permethylated Hex5Pent3Dox1 structure (XXFG) and the corresponding fragmentation pattern. (C) MALDI-TOF/TOF MS of the precursor ion at m/z = 1947·9 ([M + Na]+ adduct) of the permethylated Hex6Pent3Dox1 structure (XLFG) and the corresponding fragmentation pattern. Hex, hexose; Pent, pentose; Dox, deoxyhexose; Glc, glucose; Gal, galactose; Xyl, xylose; Fuc, fucose; *, double fragmentation ion (in B and C).
