What is Glycosylation?
Glycosylation refers back to the enzymatic technique that attaches glycans (sugar molecules) to proteins or lipids. This amendment is relevant for protein folding, stability, and characteristic. There are two primary types of glycosylation: N-linked and O-connected.
N-Linked Glycosylation
In N-associated glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This form is prevalent in many secreted and membrane-certain proteins.
O-Linked Glycosylation
O-related glycosylation entails attaching glycans to the hydroxyl workforce of serine or threonine residues. This form is quite often chanced on in mucins and different secreted proteins.
