What is Glycosylation?

Glycosylation refers back to the enzymatic strategy that attaches glycans (sugar molecules) to proteins or lipids. This amendment is a very powerful for protein folding, stability, and serve as. There are two foremost varieties of glycosylation: N-related and O-connected.

N-Linked Glycosylation

In N-linked glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This classification is familiar in many secreted and membrane-bound proteins.

O-Linked Glycosylation

O-associated glycosylation includes attaching glycans to the hydroxyl group of serine or threonine residues. This type is as a rule discovered in mucins and different secreted proteins.

The Role of Glycoproteomics in Cancer Research
