What is Glycosylation?
Glycosylation refers back to the enzymatic manner that attaches glycans (sugar molecules) to proteins or lipids. This amendment is quintessential for protein folding, steadiness, and position. There are two leading varieties of glycosylation: N-associated and O-related.
N-Linked Glycosylation
In N-linked glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This kind is favourite in many secreted and membrane-bound proteins.
O-Linked Glycosylation
O-related glycosylation contains attaching glycans to the hydroxyl organization of serine or threonine residues. This kind is ordinarilly came upon in mucins and other secreted proteins.
