What is Glycosylation?
Glycosylation refers to the enzymatic strategy that attaches glycans (sugar molecules) to proteins or lipids. This modification is primary for protein folding, stability, and function. There are two major forms of glycosylation: N-related and O-linked.
N-Linked Glycosylation
In N-associated glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This form is conventional in lots of secreted and membrane-certain proteins.
O-Linked Glycosylation
O-linked glycosylation involves attaching glycans to the hydroxyl crew of serine or threonine residues. This style is characteristically found in mucins and different secreted proteins.
