What is Glycosylation?
Glycosylation refers to the enzymatic course of that attaches glycans (sugar molecules) to proteins or lipids. This modification is indispensable for protein folding, steadiness, and characteristic. There are two leading sorts of glycosylation: N-associated and O-linked.
N-Linked Glycosylation
In N-related glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This model is favourite in many secreted and membrane-bound proteins.
O-Linked Glycosylation
O-connected glycosylation comprises attaching glycans to the hydroxyl neighborhood of serine or threonine residues. This model is in the main came across in mucins and other secreted proteins.
The Role of Glycoproteomics in Cancer Research
