Understanding Glycosylation

What is Glycosylation?

Glycosylation refers to the enzymatic process via which carbohydrates (glycans) are covalently connected to proteins or lipids. This amendment plays a quintessential function in cellular applications together with telephone signaling, immune response, and protein folding.

Types of Glycosylation

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

    The presence and architecture of glycans can outcome protein conformation, biological process, or even immunogenicity. Understanding those platforms is obligatory for constructing Click for source fantastic therapeutics.

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