Description and Uses

N-acetylneuraminic acid is an N-acyl derivative of neuraminic or acid amino sugar derivative, derived from N-acetylmannosamine and pyruvic acid. It is an important constituent of glycoproteins and glycolipids. N-acetylneuraminic acid occurs in many polysaccharides, glycoproteins, and glycolipids in animals and bacteria.

N-Acetylneuraminic acid is an integral part of sialic acids (SAs), important functional sugars that play an important role in maintaining and improving brain health, detoxification, antibacterial, and immune enhancement. n-Acetylneuraminic acid is biologically useful for neurotransmission, leukocyte extravasation, viral or bacterial infection, and carbohydrate-protein recognition. n- Acetylneuraminic acid is used to study its biochemistry, metabolism and absorption in vivo and in vitro.
