Understanding Glycosylation

What is Glycosylation?

Glycosylation refers to the enzymatic process by which carbohydrates (glycans) are covalently hooked up to proteins or lipids. This change plays a critical function in cellular services adding cell signaling, immune reaction, and protein folding.

Types of Glycosylation

  • N-linked Glycosylation: Occurs while glycans attach to nitrogen atoms in asparagine residues.
  • O-linked Glycosylation: Involves attachments to the oxygen atom in serine or threonine residues.
  • C-connected Glycosylation: A much less time-honored sort wherein sugars are linked without delay to carbon atoms on tryptophan residues.
  • Why is Glycosylation Important?

    The presence and structure of glycans can result protein conformation, biological task, or even immunogenicity. Understanding these platforms is significant for developing beneficial therapeutics.
