Implication

Spectroscopic study demonstrates linkage position determination in oligosaccharides using tandem mass spectrometry of lithium-cationized species, highlighting an analytical approach for structural...

Key Points

  • To determine the glycosidic linkage positions in oligosaccharides using tandem mass spectrometry of lithium-cationized carbohydrates.
  • Generated lithium-cationized carbohydrate complexes to facilitate gas-phase coordination.
  • Analyzed the cationized oligosaccharides using tandem mass spectrometry (MS/MS) to investigate fragmentation pathways.
  • Lithium-cationized carbohydrates yield distinct MS/MS dissociation patterns sensitive to glycosidic linkage positions.
  • Tandem mass spectrometry of lithiated adducts allows differentiation between carbohydrate structural isomers based on characteristic fragment ions.
