What is Glycosylation?
Glycosylation refers to the enzymatic strategy that attaches glycans (sugar molecules) to proteins or lipids. This change is primary for protein folding, stability, and characteristic. There are two principal sorts of glycosylation: N-associated and O-related.
N-Linked Glycosylation
In N-linked glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This category is established in lots of secreted and membrane-sure proteins.
O-Linked Glycosylation
O-related glycosylation comes to attaching glycans to the hydroxyl staff of serine or threonine residues. This model is as a rule came across in mucins and other secreted proteins.
The Role of Glycoproteomics in Cancer Research
