Active Ingredient:Sialic Acid

CAS No.:131-48-6

Structural formula:

Sialic acid (SA) is a generic term for a nine-carbon sugar neuraminic acid acylate, first isolated from salivary gland mucin by the Swedish biochemist Gunmar Blix [1], hence the name sialic acid. Sialic acid is widely found in various biological tissues and is an important component of glycoproteins, oligosaccharides and glycolipids, usually in the form of glycosides at the ends of glycoproteins and glycolipids, especially in mammalian brain, nervous tissue, blood, submandibular glands, mucin and colostrum. Sometimes, however, free sialic acid can also be found in serum, body fluids and urine [2]. The main food source of salivary acid is breast milk, especially colostrum, which is high in it. Salivary acid is also found in milk, milk powder and eggs [3-4]. Also bird's nests are known for having high levels (5.3%-11.5%) of salivary acid.
