title: Electron ionization mass spectra of reduced and permethylated urinary oligosaccharides from patients with mannosidosis.
abstract: The electron ionization mass spectra of reduced and permethylated isomeric mixtures of the major urinary tri- to deca-oligosaccharides of patients with mannosidosis are reported. Many of the oligosaccharide isomers can be differentiated in the mixtures on the basis of their distinct fragmentation patterns.
