Understanding Glycosylation

What is Glycosylation?

Glycosylation refers back to the enzymatic manner by which carbohydrates (glycans) are covalently connected to proteins or lipids. This amendment plays a relevant role in mobile capabilities together with cell phone signaling, immune reaction, and protein folding.

Types of Glycosylation

  • N-related Glycosylation: Occurs when glycans connect to nitrogen atoms in asparagine residues.
  • O-associated Glycosylation: Involves attachments to the oxygen atom in serine or threonine residues.
  • C-linked Glycosylation: A much less hassle-free shape in which sugars are connected without delay to carbon atoms on tryptophan residues.
  • Why is Glycosylation Important?

    The presence and constitution of glycans can impression protein conformation, biological job, and even immunogenicity. Understanding those structures is relevant for creating productive therapeutics.
