(3) Application
Hyaluronic acid(HA) is a straight chain macromolecular mucopolysaccharide composed of repeat disaccharide units of
glucuronic acid N-acetylglucosamin. It widely consists in the extracellular space of human animal tissue, vitreum, umbilical
cord, skin joints synovia cockscomb, etc.
The commercial HA is commonly a sodium salt, called sodium hyaluronate, habitually called hyaluronic acid. HA is a
new biological at home abroad. Its molecular weight is from several ten thousto several million. It’s aqueous solution has
outstanding moisture keeping ability, high viscoelasticity lubricity. It is widely used in cosmetics, pharmacy health beauty
food.
