2,5-Anhydro-D-glucitol is a type of biochemical reagent used in glycobiology research. Glycobiology focuses on the study of sugars’ structure, synthesis, biology, and evolution. It encompasses carbohydrate chemistry, enzymology of glycan formation and degradation, protein-glycan recognition, and the role of glycans in biological systems. This field is closely linked to fundamental research, biomedicine, and biotechnology.
