N-Acetylneuraminic acid CAS 131-48-6 Application

N-acetylneuraminic acid sialic acid (N-acyl neuraminic acid) is the most widely distributed sugar in nature, which is mainly composed of glycoproteins, glycolipids or bacterial capsule substances in animal cell membranes or secretions. In glycoproteins or glycolipids, the ketone group at position 2 forms a glycosidic bond, which makes it located at the non reducing end of the sugar side chain. Its negative charge or unique chemical structure makes it have various physiological specificity. The enzyme that hydrolyzes and removes terminal n-acetylneuraminidase (neuraminidase) is widely distributed in nature, from viruses to animals. Through the physiological activity changes of this enzyme chemicalbook, the role of this terminal acidic sugar residue has been clarified. For example, this sugar residue constitutes the binding site of influenza virus on the erythrocyte membrane and plays a major role in the mutual recognition between plasma glycoproteins and hepatocytes or the recognition mechanism of lymphocytes on the circulation pathway. Although the biosynthetic pathway is somewhat different in animals and bacteria, it all passes through N-acetylmannosamine or its 6-phosphate, which is catalyzed by specific pyrophosphatase and reacts with CTP to produce CMP-N-acetylneuraminic acid, which is incorporated into the sugar chain by glycosyl transfer reaction.
