Usage

Function of N-acetylneuraminic acid

N-acetylneuraminic acid is also known as sialic acid (SA) or bird's nest acid. Its main source is breast milk and dairy products. Including human milk, milk, goat milk, etc., the content of breast milk colostrum is the highest. The brain has the highest N-acetylneuraminic acid content in the human body, and the N-acetylneuraminic acid content in the gray matter of the brain is 15 times that of liver, lungs and other internal organs. Since its discovery in 1957, coupled with scientific research in recent years, N-acetylneuraminic acid has been shown to be of great significance to various biological functions in the body.

1. Anti-bacteria and virus

N-acetylneuraminic acid has a lot of research in related medicine, and is widely used in the field of medicine. It has a certain market scale. Like last year's popular anti-influenza drug oseltamivir in major hospital pharmacies, it came from N-acetylneuraminic acid.

N-acetylneuraminic acid can be combined with bacteria and viruses, through a certain mechanism, so as to achieve the effect of inhibition and defense. Sialic acid, as an important receptor for many pathogenic microorganisms to infect the body, provides important research ideas for the prevention of human infectious diseases.

2. Anti-inflammatory and improve immunity

N-acetylneuraminic acid can regulate the anti-inflammatory activity of IgG, thereby achieving the effect of improving immunity.
