What is Glycosylation?

Glycosylation refers to the enzymatic manner that attaches glycans (sugar molecules) to proteins or lipids. This modification is obligatory for protein folding, balance, and objective. There are two predominant styles of glycosylation: N-connected and O-connected.

N-Linked Glycosylation

In N-related glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This category is familiar in lots of secreted and membrane-bound proteins.

O-Linked Glycosylation

O-related glycosylation comprises attaching glycans to the hydroxyl group of serine or threonine residues. This style is occasionally came upon in mucins and other secreted proteins.

The Role of Glycoproteomics in Cancer Research
