Understanding Glycosylation

What is Glycosylation?

Glycosylation refers to the enzymatic course of by way of which carbohydrates (glycans) are covalently connected to proteins or lipids. This modification performs a fundamental role in cell purposes including phone signaling, immune reaction, and protein folding.

Types of Glycosylation

N-related Glycosylation: Occurs whilst glycans attach to nitrogen atoms in asparagine residues.

O-connected Glycosylation: Involves attachments to the oxygen atom in serine or threonine residues.

C-linked Glycosylation: A less favourite type in which sugars are connected directly to carbon atoms on tryptophan residues.

Why is Glycosylation Important?

The presence and layout of glycans can impact protein conformation, organic activity, and even immunogenicity. Understanding these constructions is an important for developing helpful therapeutics.
