What is Glycosylation?
Glycosylation refers back to the enzymatic technique that attaches glycans (sugar molecules) to proteins or lipids. This modification is primary for protein folding, balance, and position. There are two major kinds of glycosylation: N-connected and O-connected.
N-Linked Glycosylation
In N-associated glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This variety is customary in lots of secreted and membrane-certain proteins.
O-Linked Glycosylation
O-connected glycosylation involves attaching glycans to the hydroxyl organization of serine or threonine residues. This shape is steadily stumbled on in mucins and different secreted proteins.
