Glycobiology

Glycobiology explores the structures, biosynthesis, and biological roles of glycans — the complex carbohydrate chains that coat virtually every cell surface and decorate secreted proteins. Long overshadowed by genomics and proteomics, the glycome is now recognized as a critical layer of biological information: glycans modulate protein folding, regulate immune checkpoints, mediate pathogen invasion, and carry cancer-specific signatures that are increasingly exploited as biomarkers. The SARS-CoV-2 spike protein's dense glycan shield, which camouflages it from antibodies, brought broad scientific attention to the field. Biopharmaceutical manufacturing critically depends on glycobiology because the glycan profile of a therapeutic antibody determines its half-life and effector functions. Researchers combine organic chemistry, structural biology, cell biology, and data-science approaches to decode what remains the most chemically complex layer of the cell.
