N-Acetylneuraminic Acid (Neu5Ac), commonly known as sialic acid, is a naturally occurring monosaccharide involved in critical cellular and immune functions, including cell signaling, pathogen defense, and brain development.

Neu5Ac is widely studied for neurodevelopment, cognitive support, immune modulation, anti-inflammatory activity, viral infection inhibition (such as influenza binding prevention), and supporting gut and infant health.

It is used in glycoprotein and ganglioside biosynthesis, which plays an important role in maintaining cell membrane stability.

Neu5Ac API features high purity of ≥99%, fermentation-based production, and GMP-like quality control standards.

It is suitable for pharmaceutical, nutritional, and infant formula applications, as well as neurological, immune health, and antiviral research applications.
