What is Glycosylation?
Glycosylation refers to the enzymatic system that attaches glycans (sugar molecules) to proteins or lipids. This modification is fundamental for protein folding, balance, and functionality. There are two major kinds of glycosylation: N-associated and O-linked.
N-Linked Glycosylation
In N-related glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This fashion is widely used in lots of secreted and membrane-bound proteins.
O-Linked Glycosylation
O-associated glycosylation comes to attaching glycans to the hydroxyl group of serine or threonine residues. This sort is characteristically came upon in mucins and other secreted proteins.
