The unique interaction between the oligosaccharide chains have different applications. First, it aids in quality control by identifying misfolded proteins. The oligosaccharide chains also change the solubility and polarity of the proteins that they are bonded to. For example, if the oligosaccharide chains are negatively charged, with enough density around the protein, they can repulse proteolytic enzymes away from the bonded protein. The diversity in interactions lends it… WebOnly one oligosaccharide can be released from a glycoprotein as hydrolysate by controlled trifluoromethanesulfonic acid hydrolysis [63], the intact oligosaccharide being preserved …
