T. Yamagaki et al., POST-SOURCE DECAY FRAGMENT ANALYSIS OF A HIGHLY BRANCHED NONASACCHARIDE OF XYLOGLUCAN USING MALDI-TOF MASS-SPECTROMETRY, Chemistry Letters, (1), 1998, pp. 57-58
A highly branched nonasaccharide of xyloglucan was analyzed by MALDI-T
OFMS post-source decay fragment analysis. The fragmentation occurred o
nly at glycosidic bonds at the non-reducing terminal side of the glyco
sidic oxygen. In the MALDI-PSD fragment spectrum, almost all fragment
ions, possibly produced by a three-site cleavage, were observed. The l
arge amount of fragment mass information allowed us to determine the s
equentially fine structure of the highly branched oligosaccharide.
