Sialic acid is a carbohydrate widely existing in nature. It is also the basic component of many glycoproteins, glycopeptides and glycolipids. It has a wide range of biological functions, such as the regulation of half-life of blood proteins, the neutralization of a variety of toxins, cell adhesion, immune antigen antibody reaction and the protection of cell lysis. Biochemical derivatives of sialic acid are also commonly used in drug synthesis. N-acetylneuraminic acid n-acetylneuraminicacid is the most widely distributed sialic acid in nature, which is mainly composed of glycoproteins, glycolipids or bacterial capsule substances in animal cell membrane or secretion. 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 (neuraminidase) that hydrolyzes and removes terminal N-acetylneuraminic acid is widely distributed in nature from viruses to animals. The role of this terminal acidic sugar residue has been clarified by dealing with the physiological activity changes of this enzyme. 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 circulatory pathway. Although the biosynthetic pathways are somewhat different in animals and bacteria, they all pass through N-acetylmannosamine or its 6-phosphate, react with CTP catalyzed by specific pyrophosphatase to produce CMP-N-acetylneuraminic acid, and then be incorporated into the sugar chain by glycosyl transfer reaction.
