The price of domestic hyaluronic acid is lower than that of imported hyaluronic acid, but the maintenance time is not as long as that of imported hyaluronic acid.
Extended data:
Hyaluronic acid is a disaccharide unit composed of D- glucuronic acid and N- acetylglucosamine, also known as uronic acid and hyaluronic acid. Its basic structure is a large polysaccharide composed of two disaccharide units, D- glucuronic acid and N- acetylglucosamine. Unlike other mucopolysaccharides, it does not contain sulfur.
Hyaluronic acid is an acidic mucopolysaccharide, which was first isolated from bovine vitreous by Meyer, an ophthalmologist at Columbia University in the United States, on 1934. Hyaluronic acid, with its unique molecular structure and physical and chemical properties, has many important physiological functions in vivo, such as lubricating joints, regulating the permeability of blood vessel walls, regulating the diffusion and operation of protein, water and electrolytes, and promoting wound healing.
