Structural Formula

Sialic Acid



Sialic Acid


NZP's sialic acid (N-acetylneuraminic acid, Neu5Ac, NAN, NANA) is manufactured up to large scale to customer order.

Sialic acid is a generic term for the N- or O-substituted derivatives of neuraminic acid, a nine-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 NZP.

Sialic acids are found widely distributed in animal tissues and in bacteria, especially in glycoproteins and gangliosides. The amino group bears either an acetyl or a glycolyl group. NZP's sialic acid is a synthetic product and is the pure N-acetyl compound. Sialic acid is also found widely in endothelial tissue and elsewhere; conjugated to a range 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 known as 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 a receptor for influenza viruses to allow attachment to mucous cells (an early step in contracting the flu).

Use of Chemical

NZP's sialic acid is used in the production of several neuraminidase inhibitors, glycolipids and other synthetically derived bio-active products.
Sialic acid could find a valuable role in dietary supplements as a glyconutrient.
