Understanding Glycosylation

What is Glycosylation?

Glycosylation refers back to the enzymatic technique by way of which carbohydrates (glycans) are covalently attached to proteins or lipids. This modification performs a vital function in cellular features consisting of cellular signaling, immune reaction, and protein folding.

Types of Glycosylation N-related Glycosylation: Occurs when glycans connect to nitrogen atoms in asparagine residues. O-related Glycosylation: Involves attachments to the oxygen atom in serine or threonine residues. C-linked Glycosylation: A much less general shape the place sugars are connected quickly to carbon atoms on tryptophan residues. Why is Glycosylation Important?
