What is the purpose of N-linked Glycosylation?

#Unit 2. Cellular Organization
  1. N-linked oligosaccharide establish a “glyco-code” that marks the progression of protein unfolding.
  2. The presence of oligosaccharides tends to make a glycoprotein more susceptible to digestion by proteolytic enzymes.
  3. N-linked glycosylation making folding intermediates more soluble, thereby promoting their aggregation. 
  4. A small N-linked oligosaccharide protruding from the surface of a glycoprotein can limit the approach of other macromolecules to the protein surface.
