Gal1-β-4GlcNAc-β-Bn (Benzyl β-D-galactopyranosyl-(1→4)-β-D-N-acetylglucosamine) is a biochemical reagent employed in glycobiology research. Glycobiology focuses on exploring the structure, synthesis, biology, and evolution of sugars, encompassing areas such as carbohydrate chemistry, glycan formation and degradation enzymology, protein-glycan recognition, and the roles of glycans within biological systems. This field is closely linked to fundamental research, biomedicine, and biotechnology.
