4,7,8,9-Tetra-O-acetyl-N-acetylneuraminic acid methyl ester

4,7,8,9-Tetra-O-acetyl-N-acetylneuraminic acid methyl ester 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.
