What is Glycosylation?
Glycosylation refers to the enzymatic technique that attaches glycans (sugar molecules) to proteins or lipids. This change is primary for protein folding, stability, and position. There are two leading different types of glycosylation: N-connected and O-associated.
N-Linked Glycosylation
In N-associated glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This fashion is typical in lots of secreted and membrane-sure proteins.
O-Linked Glycosylation
O-associated glycosylation contains attaching glycans to the hydroxyl team of serine or threonine residues. This model is broadly speaking found out in mucins and different secreted proteins.
