N-5-Carboxypentyl-deoxymannojirimycin is a biochemical reagent used in glycoscience research. Glycoscience examines the structure, synthesis, biology, and evolution of sugars. This field covers carbohydrate chemistry, glycan formation and degradation enzymology, protein-glycan interactions, and the role of glycans in biological systems, and it is closely linked to fundamental research, biomedicine, and biotechnology.
