Sialic acid is a derivative of 9- carbon monosaccharide. The name comes from the Greek (sigma ι alpha lambda &western sigma (sialos) 'saliva) this is a kind of can make saliva to produce smooth feel negatively charged ions. Not only does it "induce" invading bacteria, but cognition is now a transmitter of gangliosides and a component of the brain.
Sialic acid prevents the bacteria from invading. Sialic acid is also the receptor of influenza virus, which is the binding site of influenza virus in mucus cells.
Properties: colorless crystal.
Melting point (° C) : 185-187 (decomposition)
Specific rotation (C=2, in water) : -32
Solubility: soluble in water and methanol, slightly soluble in ethanol, insoluble in ether, acetone and chloroform.
Sialic acid (SA), known as n-acetyl-neuraminic acid, is a naturally occurring carbohydrate. It was originally isolated from the mucin of the submandibular gland, hence its name. Sialic acid is usually found in the form of oligosaccharides, glycolipids, or glycoproteins. The brain has the highest amount of sialic acid in the body. The amount of sialic acid in the gray matter of the brain is 15 times that of the liver, lung and other internal organs. The main food source of sialic acid is breast milk, which is also found in milk, eggs and cheese.
