What is Glycosylation?
Glycosylation refers back to the enzymatic job that attaches glycans (sugar molecules) to proteins or lipids. This change is central for protein folding, steadiness, and operate. There are two major kinds of glycosylation: N-linked and O-related.
N-Linked Glycosylation
In N-linked glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This category is favourite in many secreted and membrane-bound proteins.
O-Linked Glycosylation
O-related glycosylation contains attaching glycans to the hydroxyl crew of serine or threonine residues. This style is recurrently observed in mucins and other secreted proteins.
