Glycobiology: Defined in the narrowest sense, glycobiology is the study of the structure, biosynthesis, and biology of saccharides (sugar chains or glycans) that are widely distributed in nature. 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.Eutherian fetoembryonic defense system (eu-FEDS) hypothesis: The Eutherian Fetoembryonic Defense System (eu-FEDS) is a hypothetical model describing a method by which immune systems are capable of recognizing additional states of relatedness like "own species" such as is observed in maternal immune tolerance in pregnancy. The model includes descriptions of the proposed signaling mechanism and several proposed examples of exploitation of this signaling in disease states.Soft laser desorption: Soft laser desorption is laser desorption of large molecules that results in ionization without fragmentation. "Soft" in the context of ion formation means forming ions without breaking chemical bonds.Atomic mass: right |thumb|200px|Stylized [[lithium-7 atom: 3 protons, 4 neutrons, & 3 electrons (total electrons are ~1/4300th of the mass of the nucleus). It has a mass of 7.Glycosylation: Glycosylation (see also chemical glycosylation) is the reaction in which a carbohydrate, i.e.Tumor-associated glycoprotein: Tumor-associated glycoproteins (TAGs) are glycoproteins found on the surface of many cancer cells. They are mucin-like molecules with a molar mass of over 1000 kDa.Disaccharide: A disaccharide or bioseBiose on www.merriam-webster.N-linked glycosylation: N-linked glycosylation, is the attachment of the sugar molecule oligosaccharide known as glycan to a nitrogen atom (amide nitrogen of asparagine (Asn) residue of a protein), in a process called N-glycosylation, studied in biochemistry. This type of linkage is important for both the structure and function of some eukaryotic proteins.
