Oligossacharide structure determination on an ion trap
- Univ. of North Carolina, Chapel Hill, NC (United States)
Oligosaccharides are important elements in intra- and inter-cellular/molecular recognition mechanisms. Linkage types are part of the information that determine the tertiary structure of oligosaccharides and the tertiary structure is what determines specific recognition, so easily obtained linkage sequences will provide valuable information for computer and other modeling of cellular signaling interactions. Hofmeister et al. have shown that lithium cationized oligosaccharides have specific MS/MS dissociation patterns indicative of the carbohydrate linkage under low energy CID conditions in a hybrid mass spectrometer. The authors have used electrospray ionization on a quadrupole ion trap mass spectrometer to examine MS/MS disaccharide dissociation patterns under ion trap conditions. These studies have concentrated on disaccharides complexed with lithium and sodium.
