Amino acids oligosaccharides

Even highly polar analytes such as underivatized amino acids, oligosaccharides, or nucleobases can be retained on these columns. 

A derivatization with acid chlorides is also possible. Amino acids can be derivatized with 9-fluorenylmethyl chloroformate (FMOC) and separated on a CSP with X-cyclodextrin (ChiraDex gamma ), a cyclic oligosaccharide which consists of eight glucose units.

Glycophorins A, B, and C are also transmembrane glycoproteins but of the single-pass type, extending across the membrane only once. A is the major gly-cophorin, is made up of 131 amino acids, and is heavily glycosylated (about 60% of its mass). Its amino terminal end, which contains 16 oligosaccharide chains (15 of which are O-glycans), extrudes out from the surface of...

Quantitative information may also be gained from the data. If the amino acid composition is accurately known, it may prove possible to integrate portions of the 13C-n.m.r. spectra in order to gain quantitative information about the oligosaccharide structure. This also assumes that no differential nuclear Overhauser effects (n.O.e. s) exist between the various resonances and that none of the resonances in question are attenuated by the use of short recycle-times.
