Metabolite Identification
Common NameN-Acetylneuraminic acid
DescriptionN-Acetylneuraminic acid, also known as N-acetylneuraminate or sialic acid, belongs to the class of organic compounds known as n-acylneuraminic acids. These are neuraminic acids carrying an N-acyl substituent. N-Acetylneuraminic acid exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. N-Acetylneuraminic acid exists in all living organisms, ranging from bacteria to humans. N-Acetylneuraminic acid participates in a number of enzymatic reactions, within cattle. In particular, N-Acetylneuraminic acid can be biosynthesized from N-acetylmannosamine and phosphoenolpyruvic acid; which is catalyzed by the enzyme sialic acid synthase. In addition, N-Acetylneuraminic acid can be converted into N-acetylmannosamine and pyruvic acid; which is mediated by the enzyme N-acetylneuraminate lyase. In cattle, N-acetylneuraminic acid is involved in the metabolic pathway called the amino sugar metabolism pathway. N-Acetylneuraminic acid is a potentially toxic compound. N-Acetylneuraminic acid has been found to be associated with several diseases known as sialidosis, normosomatic type, irritable bowel syndrome, ulcerative colitis, and colorectal cancer; also n-acetylneuraminic acid has been linked to the inborn metabolic disorders including salla disease.
