• 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.
• The numbering of the sialic acid structure begins at the carboxylate carbon and continues around the chain. The configuration which places the carboxylate in the axial position is the alpha-anomer. The alpha-anomer is the form that is found when sialic acid is bound to glycans, however, in solution it is mainly (over 90 %) in the beta-anomeric form. A bacterial enzyme with sialic acid mutarotase activity, NanM, has been discovered which is able to rapidly equilibrate solutions of sialic acid to the resting equilibrium position of around 90 % beta 10 % alpha.
• 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.
