What is Glycosylation?
Glycosylation refers to the enzymatic process that attaches glycans (sugar molecules) to proteins or lipids. This modification is crucial for protein folding, steadiness, and characteristic. There are two important sorts of glycosylation: N-connected and O-related.
N-Linked Glycosylation
In N-connected glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This form is standard in many secreted and membrane-bound proteins.
O-Linked Glycosylation
O-associated glycosylation includes attaching glycans to the hydroxyl organization of serine or threonine residues. This model is repeatedly found in mucins and other secreted proteins.
