What is Glycosylation?
Glycosylation refers back to the enzymatic system that attaches glycans (sugar molecules) to proteins or lipids. This change is integral for protein folding, stability, and objective. There are two predominant types of glycosylation: N-associated and O-related.
N-Linked Glycosylation
In N-associated glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This model is commonplace in many secreted and membrane-certain proteins.
O-Linked Glycosylation
O-related glycosylation entails attaching glycans to the hydroxyl crew of serine or threonine residues. This form is mainly determined in mucins and other secreted proteins.
