D-Mannose,3-amino-3-deoxy (hydrochloride) is a biochemical reagent used in glycobiology research. This branch of study examines the structure, synthesis, biology, and evolution of sugars, encompassing carbohydrate chemistry, glycan formation and degradation enzymology, protein-glycan recognition, and glycans' roles in biological systems. The field is closely tied to fundamental research, biomedicine, and biotechnology.
