Abstract/OtherAbstract:
The structure of glycoconjugates has been determined by several chromatographic methods, however gas chromatography-mass spectrometry (GC-MS) has been widely used to identify and quantify the volatile trimethylsilyl and fluoroacyl derivatives. Adapting the reduction/acetylation strategies, we had performed the derivatization of all monosaccharide class, as well as amino acids and OH-fatty acids as from different glycoconjugates. Uronic acids gave characteristic ions at m/z 143, 156 and 173, and 19 amino acids derivatives, gave molecular ions [M]+ and daughter ions of [M-59]+ and [M-43]+ on electron impact (EI)-MS, which provide their rapid identification.
