Uses and functions of Sialic Acid Powder

N-acetylneuraminic acid (N-acylneuraminic acid) is the most widely distributed salivary acid in nature, and is mainly a constituent sugar of glycoproteins, glycolipids, or bacterial pod membrane substances of animal cell membranes or secretion fluids.

In glycoproteins or glycolipids, due to the 2-position ketone group to form a glycosidic bond and so that it is located in the sugar side chain of the non-reducing end of the cathodic charge or the unique chemical structure so that it has a variety of physiological specificity.

Bioactive pharmacological effects of Sialic Acid Raw Powder

The role of this terminal acidic sugar residue has been clarified by processing the physiological changes in the activity of the enzyme (neuraminidase) that hydrolyse the terminal N-acetylneuraminic acid removed, which is very widely distributed in nature, from viruses up to animals.

This sugar residue, for example, constitutes the binding site for influenza viruses in the cell membrane of red blood cells and plays a major role in the mechanism of mutual recognition of plasma glycoproteins with hepatocytes or the recognition of circulating pathways by lymphocytes.

The biosynthetic pathway, although more or less different in animals and bacteria, passes through N-acetylmannosamine or its 6-phosphate ester, which is catalyzed by specific pyrophosphatase reaction with CTP to produce CMP-N-acetylneuraminic acid, which is then incorporated into the glycan chain by a glycosyltransfer reaction.

Production method of Sialic Acid Powder

Pure sialic acid is colourless, soluble in water, and does not undergo spinning in aqueous solution. Pure ethylphthalide neuraminic acid and a light ethylphthalide neuraminic acid are very stable in aqueous solution and do not change when stored at 4°C for several months.
