Taw qhia
Hyaluronic acid yog ib qho anionic, nonsulfated glycosaminoglycan faib thoob plaws hauv kev sib txuas, epithelial, thiab neural cov ntaub so ntswg. Nws yog tshwj xeeb ntawm glycosaminoglycans nyob rau hauv uas nws yog nonsulfated, cov ntaub ntawv nyob rau hauv lub plasma daim nyias nyias es tsis txhob ntawm lub Golgi apparatus, thiab yuav ua tau loj heev, nrog rau nws cov luj molecular feem ntau ncav cuag lab. Ib qho ntawm cov khoom tseem ceeb ntawm extracellular matrix, hyaluronan pab txhawb kev loj hlob ntawm tes thiab tsiv teb tsaws, thiab kuj tseem tuaj yeem koom nrog hauv kev loj hlob ntawm qee cov qog nqaij hlav malignant. Hyaluronic acid kuj yog ib feem ntawm pawg A streptococcal extracellular capsule, thiab ntseeg tau ua lub luag haujlwm hauv kev ua phem.

Functions thiab Applications
1. Hyaluronic Acid tuaj yeem siv rau hauv kev phais qhov muag, xws li kev hloov pauv ntawm pob txha, phais kab mob cataract, phais glaucoma, thiab kev phais kho cov pob txha pob txha.
2. Hyaluronic Acid kuj tuaj yeem siv los kho osteoarthritis ntawm lub hauv caug. Lawv raug tswj hwm raws li kev txhaj tshuaj rau hauv lub hauv caug sib koom ua ke, uas ntseeg tau tias yuav ntxiv cov viscosity ntawm cov kua dej sib koom ua ke, yog li lubricating qhov sib koom ua ke, cushioning lub pob qij txha, thiab ua kom muaj cov nyhuv analgesic.
3. Hyaluronic Acid kuj tau siv rau hauv kev sib txuas ntawm cov khoom siv roj ntsha rau cov ntaub ntawv kho mob. Cov scaffolds no feem ntau muaj cov proteins xws li fibronectin txuas rau Hyaluronic Acid los pab txhawb kev txav ntawm tes mus rau hauv qhov txhab.
4. Hyaluronic Acid kuj tseem siv rau hauv cov khoom siv tshuaj tiv thaiv, uas yog siv dav hauv kev phais plab thiab plab kom tiv thaiv kev ua haujlwm tom qab adhesion.
