Top Quality N-Acetylneuraminic Acid CAS 131-48-6

Product Description
SialicAcid/Nacetylneuraminic acid(Neu5Ac, NAN, NANA) is manufactured up to large scale to customer order.
Sialic Acid/N-acetylneuraminic acid is ageneric term for the N- or O-substituted derivatives of neuraminic acid, anine-carbon monosaccharide. It is also the name for the most common member of this group, N-acetylneuraminic acid (Neu5Ac or NANA) and this is the name used by CIMA.
Nacetylneuraminic acid are found widely distributed in animal tissues and in bacteria, especially in glycoproteins and gangliosides. The amino group bears either an acetyl or aglycolyl group.
N-acetylneuraminic acid is asynthetic product and is the pure N-acetyl compound.
Nacetylneuraminic acid is also found widely in endothelial tissue and elsewhere; conjugated to arange of glycoproteins and glycolipids. It is considered to be the functional part of sialyllactose found in milk and colostrum.
Despite its role of acting as "decoy" for invading pathogens, Neu5Ac is becoming knownas an agent necessary for mediating ganglioside distribution and structures in the brain.Along with involvement in preventing infections (mucus associated with mucous membranes -mouth, nose, GI, respiratory tract), Neu5Ac acts as areceptorfor influenza viruses to allow attachment to mucous cells (an early step in contracting the flu).
