Sugars, Glycans, and Oligosaccharides

An oligosaccharide is a saccharide polymer containing a relatively small number of monosaccharides, (9-hnked by glycosidic bonds. The term glycan refers to the 

Next to MALDI-MS, the use of ESt-MS is important in oligosaccharide and glycan characterization, especially because it can be combined with on-line LC separation of complex mixtures. The most important LC methods in glycan and oligosaccharide separation are HILIC [184], HPAEC, and, after derivatization by reductive amination with 2-aminobenzamide or 2-aminoacridone, RPLC on either Cjg or porous graphitized carbon materials [185].
