N-acetylneuraminic acid
N-Acetylneuraminic acid refer to a family of neuraminic acids which contain nine-carbon acidic amino monosaccharides. The most important member of the sialic acid is N-Acetylneuraminic acid (NeuAc or NANA), occurring most abundantly in glycoproteins and glycolipids.

Function
1.N-Acetylneuraminic acid plays a vital role in the research and development of carbohydrates drug. It remains hot news in the research in the synthesis and screening of bioactive substances. However, made especially in the metastasis, anti-Alzheimer, anti-virus, anti-inflammatory and so on. A new generation of anti-influenza drug used sialic acid as a precursor is on the market now. And an anti-Alzheimer drug will also be available soon. Scientists have already proved that sialic acid is the important nutrition to the brain and peripheral nerve.
2.N-Acetylneuraminic acid is already on the market about the application of in functional foods.
3.N-Acetylneuraminic acid adds infant milk powder can increase baby's’ intelligence and memory
4.N-Acetylneuraminic acid has the function of Anti-inflammation, Enhancing human immunity
6.N-Acetylneuraminic acid is known as the mental development of "brain gold"
7.N-Acetylneuraminic acid can be Used for cosmetics, food, health supplements.
Application
N-Acetylneuraminic acid is used in the production of several neuraminidase inhibitors, glycolipids, and other synthetically derived bio-active products.
N-Acetylneuraminic acid could find a valuable role in dietary supplements as a glyconutrient.
N-Acetylneuraminic acid is usually called sialic acid or Neu5Ac, naturally widespread carbohydrate with numerous biological functions, including blood protein half-life reg Acidulation, variety of toxin neutralization, cellular adhesion, and glycoprotein lytic protection.
Starting reagent of biochemical derivatives for the synthesis pharmaceuticals.
