What is Glycosylation?
Glycosylation refers back to the enzymatic course of that attaches glycans (sugar molecules) to proteins or lipids. This change is important for protein folding, balance, and purpose. There are two essential varieties of glycosylation: N-linked and O-associated.
N-Linked Glycosylation
In N-linked glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This variety is customary in lots of secreted and membrane-bound proteins.
O-Linked Glycosylation
O-associated glycosylation comprises attaching glycans to the hydroxyl neighborhood of serine or threonine residues. This shape is typically came upon in mucins and other secreted proteins.
