Description

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. Sialic acid is a generic term for the N- or O-substituted derivatives of neuraminic acid, a monosaccharide with a nine-carbon backbone.It is also the name for the most common m

Aceneuramic acid is an N-acetylneuraminic acid that is keto-neuraminic acid in which one of the hydrogens of the amino group is replaced by an acetyl group. It is a member of N-acetylneuraminic acids, a member of acetamides and a 2-oxo monocarboxylic acid. It derives from a keto-neuraminic acid. It is a conjugate acid of an aceneuramate.|Aceneuramic acid has been used in trials studying the treatment of Distal Myopathy, Nonaka Type, Hereditary Inclusion Body Myopathy, and Distal Myopathy With Rimmed Vacuoles.|An N-acyl derivative of neuraminic acid. N-acetylneuraminic acid occurs in many polysaccharides, glycoproteins, and glycolipids in animals and bacteria. (From Dorland, 28th ed, p1518)
