Product name: N-Acetylneuraminic acid(NANA)
Other name: Sialic acid(SA)
CAS No.:131-48-6
Molecular Formula: C11H19NO9
Molecular Weight: 309.27

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.
