Do You Know The Magical Funcation Of Sialic Acid?

Sialic acid is a naturally occurring carbohydrate isolated from submandibular gland mucin, widely distributed in animal tissues, and present in small amounts in some organisms.

Sialic acid is an important component of gangliosides in the brain, which has the function of "inducing" and preventing the invasion of germs. It is usually located in the key position of the carbohydrate part of the outermost layer of the cell membrane and the secreted carbohydrate complexes (glycolipids, glycoproteins and polysaccharides), and is an important material basis for the diversification of the structure and function of carbohydrate complexes.

Ranking of sialic acid content in food

The main food source of sialic acid is breast milk, but it is also found in milk, eggs and cheese.

According to the analysis of research data, the content of sialic acid in bird's nest is fifty times that of ordinary substances.

In addition, there are many other foods containing sialic acid, and the foods with relatively rich content mainly include: loquat (0.66g/kg), eggplant (0.45g/kg), casein (4.80g/kg), milk (0.45-0.66g /kg). However, their sialic acid content is far lower than that of bird's nest, which is 70-120g/kg, up to 12%. Because of this, sialic acid is also called "bird's nest acid".

From the perspective of the human body, what are the medical functions of sialic acid?

1. Help children's intellectual development

Sialic acid improves the response speed of brain nerve cell synapses through the interaction with brain cell membranes and synapses, thereby promoting the development of memory and intelligence.

New Zealand scientists have done a group of experiments to confirm the important role of sialic acid in children's intellectual development. Finally, the experiment concluded that supplementing sialic acid in infants can increase the concentration of sialic acid in the brain, thereby improving the learning ability of the brain.

2. Promote intestinal antibacterial detoxification

Sialic acid on cell membrane proteins plays a key role in improving cell recognition ability, detoxifying cholera toxin, preventing infection of pathological Escherichia coli, and regulating the half-life of blood proteins.

3. Improve immunity

Bird's nest is rich in water-soluble protein, carbohydrates, trace elements, such as: calcium, phosphorus, iron, sodium, potassium and 8 kinds of Amino Acids necessary for the human body. Bird's nest also contains a large amount of mucin and glycoprotein, which can moisten the lungs The effect of nourishing kidney yin and tonifying deficiency and damage can enhance the body's resistance to diseases, and help resist colds, coughs and colds, especially for children.

4. Prolong life

Sialic acid has a protective and stabilizing effect on cells, and the lack of sialic acid can lead to the reduction of blood cell life and glycoprotein in metabolism. Moderate consumption of bird's nest can supplement sialic acid.
