What is Glycosylation?

Glycosylation refers back to the enzymatic procedure that attaches glycans (sugar molecules) to proteins or lipids. This modification is quintessential for protein folding, stability, and objective. There are two predominant sorts of glycosylation: N-linked and O-connected.

N-Linked Glycosylation

In N-related glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This fashion is commonly used in many secreted and membrane-bound proteins.

O-Linked Glycosylation

O-related glycosylation comes to attaching glycans to the hydroxyl organization of serine or threonine residues. This style is recurrently came across in mucins and different secreted proteins.

The Role of Glycoproteomics in Cancer Research

Glycoproteomics makes a speciality of studying the systems and services of glycoproteins. In cancer study, it serves as a valuable device for gaining knowledge of biomarkers that may cause early detection and superior therapeutic processes.
