What is Glycosylation?
Glycosylation refers back to the enzymatic procedure that attaches glycans (sugar molecules) to proteins or lipids. This amendment is very important for protein folding, steadiness, and position. There are two major sorts 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 category is generic in many secreted and membrane-bound proteins.
O-Linked Glycosylation
O-linked glycosylation includes attaching glycans to the hydroxyl staff of serine or threonine residues. This shape is pretty much determined in mucins and different secreted proteins.
