Sialic acid (SA), known as "N-acetylneuraminic acid", is a naturally occurring carbohydrate. It was originally isolated from the mucin of the submandibular gland, hence its name. Sialic acid is usually present in the form of oligosaccharides, glycolipids, or glycoproteins. The brain has the highest level of sialic acid in the human body. The content of sialic acid in the gray matter of the brain is 15 times that of internal organs such as the liver and lungs. The main food source of sialic acid is breast milk, which is also present in milk, eggs, and cheese.
Pure sialic acid is colorless, easily soluble in water, and does not undergo spin change in aqueous solution. Pure and light glyptocyanine are stable in aqueous solution and do not change after storage at 4 ℃ for several months.
N-Acetylneuraminic acid is a sialic acid monosaccharide commonly found in glycoproteins of cell membranes and glycolipids of mammalian cell ganglia. It plays a biological role in neurotransmission, leukocyte blood vessel exudation, and viral or bacterial infections.
1. N-acetylneuraminic acid can regulate immunity, enhance immunity, and then play the role of anti-virus and anti infection.
2. N-acetylneuraminic acid can promote the development of infant nervous system, improve the level of intellectual development, and enhance learning and memory. Adequate sialic acid intake during pregnancy has a good effect on the development of fetal intelligence and nervous system. It can prevent senile dementia for the elderly.
3. N-acetylneuraminic acid can play a role in beautifying and delaying aging.
