4-Nitrobenzyl 2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopryranoside

4-Nitrobenzyl 2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopryranoside is a class of biochemical reagents used in glycobiology research. Glycobiology studies the structure, synthesis, biology, and evolution of sugars. It involves carbohydrate chemistry, enzymology of glycan formation and degradation, protein-glycan recognition, and the role of glycans in biological systems. This field is closely related to basic research, biomedicine, and biotechnology.
