Glycoproteomics is the large-scale study of glycoproteins. Glycoproteins are proteins that have oligosaccharide chains (glycans) covalently attached to amino acid side chains. This process, known as glycosylation, is one of the most common and complex post-translational modifications of proteins. Glycosylation can significantly affect a protein's structure, function, stability, and localization.

The field of glycoproteomics aims to identify and characterize the glycan structures present on proteins and to understand how these modifications influence biological processes. This involves developing and applying sophisticated analytical techniques, often combining mass spectrometry with chromatographic methods. Techniques like lectin affinity chromatography, enzymatic deglycosylation, and various mass spectrometry-based workflows are used to isolate, purify, and analyze glycoproteins and their attached glycans.

Understanding the human glycoproteome is crucial because aberrant glycosylation is associated with numerous diseases, including cancer, inflammatory disorders, and infectious diseases. By studying the changes in protein glycosylation patterns during disease development, researchers hope to identify novel biomarkers for early diagnosis, prognosis, and therapeutic targets. Furthermore, glycoproteomics plays a vital role in understanding fundamental biological processes such as cell-cell recognition, immune response, and protein folding. The complexity of the glycoproteome, with its vast diversity of glycan structures, presents significant challenges but also offers rich opportunities for biological discovery.
