HA is the maincomponent composing human intercellular substance, vitreum joints synovia, etc.

It can retain water, keep intercellular space, accommodate osmotic pressure,lubricate and further rehabilitation of cells.



In its aqueous solution, a mountof carboxyl and hydroxy in its molecular, which can form hydrogen bondings inmolecule and between molecules, thus making it a powerful water keeping action.



It can bond water over 400 multiple. In upper consistence, HA aqueous solutionhas high viscoelasticity because of its molecules form complex three reticulagrades.


As a main component of intercellular substance, HA directly concernsthe transfer of exchange of electrolyte inside and outside cells, demonstratesthe filter action of physical and molecule information.

Macromolecule HA canprevent cells from move, hyperplasia, disintegration and engulfment, while lowolecule HA has furtherance actions.

HA has peculiar physical and chemical property and biologic action, widely usedin medicine. It can be used as a viscoelastic agent in artificial crystalplanting in ocular surgery, as a fill agent in osteoarthritis, also as an agentin eye drops.

It has good action of adhesion preventives in surgericaloperations and healing cuts on skin.
Compound of HA and other drug, theadditive can make the action of drug delaying. With the development of medicaltechnology. HA will be more widely used in medicine.
