What is Glycosylation?
Glycosylation refers back to the enzymatic manner that attaches glycans (sugar molecules) to proteins or lipids. This amendment is imperative for protein folding, balance, and function. There are two leading varieties of glycosylation: N-related and O-linked.
N-Linked Glycosylation
In N-associated glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This classification is generic in lots of secreted and membrane-certain proteins.
O-Linked Glycosylation
O-associated glycosylation contains attaching glycans to the hydroxyl community of serine or threonine residues. This kind is usally came across in mucins and different secreted proteins.
