What is Glycosylation?
Glycosylation refers back to the enzymatic task that attaches glycans (sugar molecules) to proteins or lipids. This change is mandatory for protein folding, steadiness, and functionality. There are two important kinds 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 classification is familiar in lots of secreted and membrane-bound proteins.
O-Linked Glycosylation
O-associated glycosylation comes to attaching glycans to the hydroxyl staff of serine or threonine residues. This shape is ceaselessly discovered in mucins and other secreted proteins.
