Understanding Glycosylation

What is Glycosylation?

Glycosylation refers to the enzymatic method via which carbohydrates (glycans) are covalently connected to proteins or lipids. This amendment plays a fundamental function in mobile applications such as mobilephone signaling, immune reaction, Discover more and protein folding.

Types of Glycosylation

  • N-connected 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-associated Glycosylation: A less easy style wherein sugars are associated in an instant to carbon atoms on tryptophan residues.
