What is Glycosylation?
Glycosylation refers to the enzymatic job that attaches glycans (sugar molecules) to proteins or lipids. This amendment is indispensable for protein folding, balance, and purpose. There are two important forms of glycosylation: N-related and O-associated.
N-Linked Glycosylation
In N-related glycosylation, glycans connect to the nitrogen Learn here atom of asparagine residues in a protein. This model is customary in many secreted and membrane-certain proteins.
O-Linked Glycosylation
O-linked glycosylation involves attaching glycans to the hydroxyl team of serine or threonine residues. This form is probably discovered in mucins and other secreted proteins.
