N-Acetylneuraminic acid
Sialic acid, the scientific name N-acetylneuramic acid (Neu5Ac), is a nitrogen-containing nine-carbon monosaccharide derivative,
which is the general term for neuramic acid and its derivatives.
Sialic acid is widely distributed in nature and exists in many organisms, especially in mammals.
In the human body, the brain nerve tissue has the highest content of sialic acid,
its content is 15 times that of the liver, lungs and other internal organs.
Sialic acid is one of the important monosaccharides of oligosaccharides in biofilms.
Most of them bind to membrane proteins and distribute on the surface of the plasma membrane
to form a polysaccharide protein complex. Because of the negative charge on the surface of sialic acid,
it plays an important role in the reception of external information and mutual recognition between cells

Function of N-Acetylneuraminic acid
1.Promote memory and intelligence development:
By interacting with brain cell membranes and synapses, bird's nest acid increases the reaction speed of brain nerve cell synapses,
thus promoting memory and intelligence development.
2.Enhance immunity:
N-Acetylneuraminic acid can enhance the function of the immune system, especially for children's immunity has significantly improved.
3.Improve intestinal absorption capacity:
N-Acetylneuraminic acid has a strong negative charge and can be combined with positively charged minerals
and some vitamins to improve the intestinal absorption capacity of these nutrients.
4.Antiviral effect:
N-Acetylneuraminic acid in vivo can enhance cell recognition, detoxification, prevention of infection, etc.,
has a certain antiviral effect.
5.Beauty skin:
N-Acetylneuraminic acid has antioxidant effect, can inhibit tyrosinase activity, help to whiten spots,
increase skin elastin production, achieve firming and anti-wrinkle effect.
6.Enhance intestinal antibacterial and detoxification ability:
N-Acetylneuraminic acid has antibacterial, antiviral and detoxification effects in the intestine,
helping to improve intestinal resistance
7.Anti-aging:
N-Acetylneuraminic acid helps maintain the health of red blood cells and epidermal cells, slows down the aging process,
and has a positive effect on maintaining the appearance.
8.Other effects:
N-Acetylneuraminic acid also has the effect of improving myocardial contractile function and avoiding cardiac decline
