p-Nitrophenyl β-D-cellobioside heptacetate is a biochemical reagent used in glycobiology research. Glycobiology focuses on the study of the structure, synthesis, biology, and evolution of sugars. This field encompasses carbohydrate chemistry, glycan formation and degradation enzymology, protein-glycan recognition, and the role of glycans in biological systems. It is closely linked to basic research, biomedicine, and biotechnology.
