Sialic acids refer to a family of neuraminic acids which contain nine-carbon acidic amino monosaccharides. The most important member of the sialic acid is N-Acetylneuraminic acid (NeuAc or NANA), occurring most abundantly in glycoproteins and glycolipids.Among all types of sialic acids, only N-Acetylneuraminic acid can be found in human tissues. Therefore, sialic acid, to human beings, refer to NANA. SA manufacture will be carried out using biocatalytic process. The micro-organism cells catalyse two substrates N-acetylglucosamine and pyruvate to biosynthesize SA in a water solution, which is subsequently concentrated and crystalysed. SA will be recrystalised as the refinery process.
Sialic Acid/N-acetylneuraminic 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 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 a glycolyl group.
