Product Description

 

Product Description

Hyaluronic acid (hyaluronic acid) is a white amorphous solid, odorless, tasteless, and hygroscopic. It is soluble in water and insoluble in organic solvents. Aqueous solution than the curl is - 70 ° to 80 °. The most prominent is the high viscosity property, the viscosity of its solution, under the following circumstances, can occur irreversible decline: pH value below or above 7; Hyaluronidase exists; Many reducing substances such as cysteine, pyrogallic acid, ascorbic acid or heavy metal ions are present; (4) ultraviolet radiation, electron beam irradiation, etc. "A high polymer composed of disaccharide repeat units of (1→3) -2-acetylamino-2-deoxy-β-D-glucose -(1→4) -O-β-D-glucuronic acid that, when hydrolyzed, yields a hexosamine (e.g., glucosamine) and a uronic acid (e.g., glucuronic acid)." It used to be a biochemical reagent, but now it has become a biochemical drug with high clinical value. In nature, it is widely found in various tissues of animals: connective tissue, umbilical cord, skin, human serum, chicken comb, joint synovial fluid, brain, cartilage, eye vitreous body, human urine, chicken embryo, rabbit egg, artery and vein wall. Hyaluronic acid is often bound to proteins and coexists with other mucopolysaccharides. In the vitreous and synovial fluid, it is present as a dissolved form, and in the comb and umbilical cord as a gel. [1] Hyaluronic acid is a linear polysaccharide structure composed of repeated structures of N-hexamylglucosamine and D-glucuronic acid.
