What is Glycosylation?
Glycosylation refers to the enzymatic strategy that attaches glycans (sugar molecules) to proteins or lipids. This modification is indispensable for protein folding, stability, and objective. There are two predominant different types of glycosylation: N-linked and O-associated.
N-Linked Glycosylation
In N-connected glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This class is primary in lots of secreted and membrane-certain proteins.
O-Linked Glycosylation
O-connected glycosylation consists of attaching glycans to the hydroxyl crew of serine or threonine residues. This sort is usally chanced on in mucins and other secreted proteins.
