Glycomics, or glycobiology is a discipline of biology that deals with the structure and function of oligosaccharides (chains of sugars). The term glycomics is derived from the chemical prefix for sweetness or a sugar, "glyco-", and was formed to follow the naming convention established by genomics (which deals with genes) and proteomics (which deals with proteins). The identity of the entirety of carbohydrates in an organism is thus collectively referred to as the glycome.
