Nusacco®(Sialic Acid)

The generic term of sialic acid is N-acetylneuraminic acid, which is a naturally occurring amino sugar that was originally isolated from the submandibular gland mucin, hence the name sialic acid. Sialic acid is a nine-carbon monosaccharide derivative containing an amino group and is a general term for all N- or O-derivatives of neuraminic acid or keto-deoxyindansyl acid (KDN). It is usually present in the form of oligosaccharides, glycolipids or glycoproteins, mainly in the form of short-chain residues at the ends of glycoproteins and glycolipids.

The main sources of sialic acid are breast milk and dairy products. Including human milk, milk, goat milk, yogurt, the highest content of breast milk colostrum, can reach 1.5 g / liter or more, the average sialic acid content in skim milk powder is 172 mg / 100 g. Another important source of sialic acid is egg food. In egg white, the content of sialic acid is 0.2 to 0.3%. In humans the brain has the highest sialic acid concentration, where these acids play an important role in neural transmission and ganglioside structure in synaptogenesis.

The history of sialic acid in China

Human consumption of sialic acid-containing foods has a long history. The main source of sialic acid is breast milk, dairy products and egg foods, so it can be said that from the moment humans appear on the earth, we are eating sialic acid. Since ancient times, China has had the habit of eating bird's nest. Bird's nest has been listed as a precious tonic. Since the Ming and Qing Dynasties, it has been hailed as the sacred product of beauty. As early as in the Tang Dynasty, China has used bird's nest as an edible treasure. It is the same as the bear's paw and shark's fin. Li Shizhen of the Ming Dynasty praised the bird’s nest in the "Compendium of Compendium of Materia Medica". In Southeast Asia and Japan, bird's nest is also a household nutritional supplement. In bird's nest, the main component of its biological activity, "bird's nest acid", is actually the common name of sialic acid, and its content is as high as 10% or more. The main function of bird's nest is reflected by sialic acid. The experiment also proves that the physiological function of bird's nest acid is as follows: it has the effect of antibacterial detoxification in the intestine; it can improve the absorption capacity of the intestine for vitamins and minerals; because it has the protection and stability effect on cells, it has the effect of prolonging life. Sialic acid develops a range of health supplements for babies, pregnant women, students and the elderly.
