What is Glycosylation?
Glycosylation refers to the enzymatic technique that attaches glycans (sugar molecules) to proteins or lipids. This amendment is obligatory for protein folding, stability, and role. There are two leading kinds of glycosylation: N-linked and O-linked.
N-Linked Glycosylation
In N-connected glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This sort is customary in many secreted and membrane-sure proteins.
O-Linked Glycosylation
O-linked glycosylation consists of attaching glycans to the hydroxyl workforce of serine or threonine residues. This sort is on the whole determined in mucins and different secreted proteins.
