Understanding Glycosylation

What is Glycosylation?

Glycosylation refers to the enzymatic manner by way of which carbohydrates (glycans) are covalently attached to proteins or lipids. This amendment performs a indispensable function in mobile capabilities including cellphone signaling, immune response, and protein folding.

Types of Glycosylation

N-linked Glycosylation: Occurs while glycans connect 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 wide-spread type in which sugars are associated straight to carbon atoms on tryptophan residues.

Why is Glycosylation Important?

The presence and architecture of glycans can result protein conformation, organic process, and even immunogenicity. Understanding those systems is valuable for developing triumphant therapeutics.
