What is Glycosylation?
Glycosylation refers to the enzymatic approach that attaches glycans (sugar molecules) to proteins or lipids. This change is needed for protein folding, balance, and position. There are two principal varieties of glycosylation: N-connected and O-related.
N-Linked Glycosylation
In N-connected glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This category is everyday in lots of secreted and membrane-certain proteins.
O-Linked Glycosylation
O-related glycosylation consists of attaching glycans to the hydroxyl workforce of serine or threonine residues. This shape is quite often observed in mucins and different secreted proteins.
