It is now recognized that many proteins are in fact glycosylated, (1) and that the attached carbohydrate chains or glycans can have significant effects on the physical properties and biological activity of the protein (2, 3). The detection of carbohydrates in glycoconjugates, and in particular in glycoproteins, is therefore a subject which is increasingly being addressed by researchers. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
