D-Glucosamine 6-phosphate (sodium) (GlcN6P-Na) is a biochemical reagent utilized in glycobiology research. This field studies the structure, synthesis, biology, and evolution of sugars, encompassing carbohydrate chemistry, glycan formation and degradation, protein-glycan interactions, and the roles of glycans in biological systems. Glycobiology is closely linked to fundamental research, biomedicine, and biotechnology.
