Understanding Glycosylation

What is Glycosylation?

Glycosylation refers back to the enzymatic method through which carbohydrates (glycans) are covalently hooked up to proteins or lipids. This modification performs a integral position in mobile services along with cellular signaling, immune reaction, and protein folding.

Types of Glycosylation

  • N-connected Glycosylation: Occurs when glycans attach to nitrogen atoms in asparagine residues.
  • O-connected Glycosylation: Involves attachments to the oxygen atom in serine or threonine residues.
  • C-related Glycosylation: A much less common sort in which sugars are related quickly to carbon atoms on tryptophan residues.
  • Why is Glycosylation Important?

    The presence and construction of glycans can outcomes protein conformation, biological undertaking, and even immunogenicity. Understanding those structures is an important for creating fantastic therapeutics.

    Analyzing Glycosylation Profiles with Mass Spectrometry: A Game Changer in Bioconjugation and Drug Development
