  4. Application:
  HA is major components in human stromal cells, vitreous, synovial fluid and other connective tissue in the body
  HA plays an important role in retaining water, maintain extracellular space, adjusting osmotic pressure, lubricating
  and improving cells reparation. Hyaluronic acid molecule contains a large number of hydroxyl groups ,in can form
  hydrogen bonds intra-molecular and inter-molecular in aqueous solution, which offers a powerful water retention function to combine more than 400 times
  volumn water. At relatively higher concentration, its aqueous solution has remarkable viscoelasticity due to the
  complicated third-class reticular structure formed through the interaction of molecules. As a major components of intercellular substance,
  HA directly takes part in electrolyte alternate control between cells and exerts the function of message filter of physics
  and molecule. High molecular HA can restrain the movement, multiplication and phagocytosis of cells while low
  molecular HA plays a role of stimulation.
  \ HA has unique physicochemical properties and physiological functions. It has been widely applied in the pharmaceutical
  industry. HA can be used as viscoelastic materials in intraocular lens implantation and as fillers in articular surgery
  against osteoarthritis, rheumatoid arthritis etc. It is also used as medium in eye drops extensively. Furthermore, HA
  is helpful in preventing post-surgery conglutination and improving wound healing. The compound as a result of its reaction to other medicine may
  play a role of sustained release, thus achieving the purpose of targeted and timed release. With the development of
  medical science, HA will become more and more useful in the field of medicine.
