Distinguishing Glucuronic from Iduronic Acid in Glycosaminoglycan Tetrasaccharides by Using Electron Detachment Dissociation

Distinguishing the epimers iduronic acid (IdoA) and glucuronic acid (GlcA) has been a long-standing challenge for the mass spectrometry analysis of glycosaminoglycan (GAG) oligosaccharides. In this work, electron detachment dissociation (EDD) and Fourier transform ion cyclotron resonance mass spectr...
