N-Acetylneuraminic Acid(Sialic Acid) CAS 131-48-6

Sialic acid is a carbohydrate widely found in nature and is the basic component of many glycoproteins, glycopeptides and glycolipids.

Description

Sialic acid has various biological functions, such as regulating the half-life blood protein, neutralizing the toxins, cell adhesion, antigen-antibody response of immunity, and protection against cell lysis.

Functions:
1. Anti-virus
2. Anti-cancer
3. Anti-tumor
3. Anti-inflammation, which has a defensive function against bacteriological infection
5. Enhance human immune function
6. Pigmentation prevention, anti-aging, and skin moisturizing in cosmetics.
7. Signal transformation in nerve cells
8. Play a key role in brain development, memory, and learning, which can treat Alzheimer’s disease
9. As a precursor for the manufacture of many pharmaceutical drugs
