Understanding Glycosylation

What is Glycosylation?

Glycosylation refers to the enzymatic manner through which carbohydrates (glycans) are covalently connected to proteins or lipids. This modification performs a mandatory role in mobile applications which include mobile phone signaling, immune response, and protein folding.

Types of Glycosylation

  • N-linked Glycosylation: Occurs while glycans attach to nitrogen atoms in asparagine residues.
  • O-associated Glycosylation: Involves attachments to the oxygen atom in serine or threonine residues.
  • C-related Glycosylation: A much less standard model wherein sugars are related right away to carbon atoms on tryptophan residues.
  • Why is Glycosylation Important?

    The presence and format of glycans can affect protein conformation, organic undertaking, and even immunogenicity. Understanding those platforms is central for creating robust therapeutics.
