Glycoproteomics is a branch of proteomics that identifies, catalogs, and characterizes proteins containing carbohydrates as a result of post-translational modifications. Glycosylation is the most common post-translational modification of proteins, but continues to be the least studied on the proteome level.
Glycoproteomics is a subset of proteomics focused on identifying and characterizing proteins with carbohydrate components added after they are synthesized. Glycosylation, the most frequent such modification, has not been extensively examined within the context of the entire protein repertoire.
