N-Acetylneuraminic Acid (Sialic Acid) is an important functional carbohydrate widely found in human milk oligosaccharides (HMOs), glycoproteins, and gangliosides. It plays a key role in brain development, immune function, and cellular communication.
Chibio Biotech offers two production routes for Sialic Acid:
Premium Non-GMO fermentation route – produced through polysialic acid intermediate hydrolysis.
Cost-efficient fermentation route – directly produced by microbial fermentation.
Both products achieve ≥98% purity, while offering different advantages in purity control, natural origin positioning, and production cost.
