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.
