What is Glycosylation?
Glycosylation refers to the enzymatic strategy that attaches glycans (sugar molecules) to proteins or lipids. This modification is important for protein folding, steadiness, and characteristic. There are two principal styles 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 fashion is regular in many secreted and membrane-certain proteins.
O-Linked Glycosylation
O-associated glycosylation includes attaching glycans to the hydroxyl crew of serine or threonine residues. This style is basically observed in mucins and other secreted proteins.
