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.
The study of glycoproteins involves identifying, documenting, and analyzing proteins that have carbohydrate molecules attached as a result of post-translational changes. Despite being the most common type of modification, glycosylation remains relatively unexplored in terms of its role in the overall protein structure.
