N-Acetylneuraminic acid



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.
