Researchers describe advances in mass spectrometry analysis to improve identification of glycopeptides

Glycosylation is the attachment of carbohydrates to the backbone of a protein through an enzymatic reaction. It plays a critical role in determining protein structure, function and stability. A protein that is glycosylated is known as a glycoprotein. The two most common types of protein glycosylation are known as N-glycosylation and O-glycosylation.
