N-linked glycan mass
WebJan 13, 2024 · Background Glycans play critical roles in a number of biological activities. Two common types of glycans, N-linked and O-linked, have been extensively analyzed in the last decades. N-glycans are typically released from glycoproteins by enzymes, while O-glycans are released from glycoproteins by chemical methods.

The terms glycans and polysaccharides are defined by IUPAC as synonyms meaning "compounds consisting of a large number of monosaccharides linked glycosidically". However, in practice the term glycan may also be used to refer to the carbohydrate portion of a glycoconjugate, such as a glycoprotein, glycolipid, or a proteoglycan, even if the carbohydrate is only an oligosaccharide. Glycans usually consist solely of O-glycosidic linkages of monosaccharides. For example, cellulo… WebJun 17, 2024 · N-linked glycosylation is one of the most important protein post-translational modifications.

WebThe presence of sialic acid (N-acetyl neuraminic acid) also affects both the mass and charge of a glycoprotein. N-linked oligosaccharides may contribute 3.5 kDa or more per structure to the mass of a glycoprotein ( Figure 1 ). O-linked sugars, although usually less massive than N-linked structures, may be more numerous ( Figures 2 and 3 ).
