What is Glycosylation?
Glycosylation refers back to the enzymatic course of that attaches glycans (sugar molecules) to proteins or lipids. This modification is valuable for protein folding, stability, and objective. There are two leading kinds of glycosylation: N-related and O-associated.
N-Linked Glycosylation
In N-related glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This fashion is primary in many secreted and membrane-certain proteins.
O-Linked Glycosylation
O-associated glycosylation comes to attaching glycans to the hydroxyl staff of serine or threonine residues. This variety is almost always chanced on in mucins and different secreted proteins.
