  Detailed Description:

1.Discovery of HA:In 1934, Karl Meyer isolated a formerly unknown glycosaminoglycan from the vitreous humor of the bovine eye. It differed from any of the other previously discovered glycosamlnoglycans in that it did not contain sulffur. With its distinctive structure, its function within the body was unique. It was named hyaluronan and further scientific study ensued. At the time of its discovery, the new compound took on two names: hyaluronan when referring to its endogenous synthesis and hyaluronic acid when discussing research conducted outside of the body-huma or animal. Today hyaluronan is comonly referred to as hyaluronic acid, regardless of the context in which it is spoken.
2.Structure of HA:Hyaluronic Acid is linear, unbranched, high molecular weight polysaccharides containing a repeating disaccharide unit (D-glucuronic acid and N-acetyl glucosamine). HA, in its natural state, weighs about from 0.5-3.0 million daltons. Its weight lends itself to high viscosity and excellent lubrication within the body. The other glycosaminoglcans in the body include chondroitin sulfate, keratan sulfate, dermatan sulfate, and heparin sulfate.
3. Distribution of HA:HA widely consists in the extracelluar spaces of animal tissue. Almost kinds of animal tissue contain the different quantity of HA. Today Hyaluronic Acid has been found from skin, cockcomb, brain, vitreum, connective tissue, umbilical cord, human serum, articular fluid, gristle, human urine, cock embryo, oocyte, artery and vein etc.
