What is Glycosylation?
Glycosylation refers to the enzymatic system that attaches glycans (sugar molecules) to proteins or lipids. This modification is critical for protein folding, balance, and feature. There are two important kinds of glycosylation: N-associated and O-related.
N-Linked Glycosylation
In N-associated glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This class is primary in many secreted and membrane-certain proteins.
O-Linked Glycosylation
O-associated glycosylation contains attaching glycans to the hydroxyl group of serine or threonine residues. This model is as a rule chanced on in mucins and other secreted proteins.
