Understanding Glycosylation

What is Glycosylation?

Glycosylation refers to the enzymatic process with the aid of which carbohydrates (glycans) are covalently connected to proteins or lipids. This modification plays a valuable function in cell purposes such as cellular phone signaling, immune reaction, and protein folding.

Types of Glycosylation

  • N-connected Glycosylation: Occurs while glycans attach to nitrogen atoms in asparagine residues.
  • O-connected Glycosylation: Involves attachments to the oxygen atom in serine or threonine residues.
  • C-connected Glycosylation: A much less regularly occurring form the place sugars are linked promptly to carbon atoms on tryptophan residues.
  • Why is Glycosylation Important?

    The presence and format of glycans can have an effect on protein conformation, biological process, or even immunogenicity. Understanding those constructions is indispensable for developing strong therapeutics.
