Glycobiology: the study of the structure, biosynthesis, and biology of saccharides that are widely distributed in nature. Glycans play crucial roles in constructing complex multicellular organs and organisms, a process that requires interactions of cells with one another and with the surrounding extracellular matrix. Sugars or saccharides are essential components of all living things and aspects of the various roles they play in biology are researched in various medical, biochemical and biotechnological fields.
