What is Glycosylation?
Glycosylation refers to the enzymatic course of that attaches glycans (sugar molecules) to proteins or lipids. This change is necessary for protein folding, steadiness, and serve as. There are two essential styles of glycosylation: N-connected and O-associated.
N-Linked Glycosylation
In N-related glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This variety is accepted in lots of secreted and membrane-bound proteins.
O-Linked Glycosylation
O-linked glycosylation comes to attaching glycans to the hydroxyl community of serine or threonine residues. This shape is ceaselessly chanced on in mucins and other secreted proteins.
