What is Glycosylation?
Glycosylation refers to the enzymatic approach that attaches glycans (sugar molecules) to proteins or lipids. This modification is an important for protein folding, balance, and position. There are two principal types of glycosylation: N-connected and O-connected.
N-Linked Glycosylation
In N-connected glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This sort is standard in lots of secreted and membrane-certain proteins.
O-Linked Glycosylation
O-linked glycosylation comes to attaching glycans to the hydroxyl community of serine or threonine residues. This type is broadly speaking found out in mucins and other secreted proteins.
