Calcium Hydroxyapatite HAP CAS 1306-06-5
Hydroxyapatite, kuj huhydroxylapatite(HA), yog ib daim ntawv uas tshwm sim los ntawm calcium apatite nrog cov mis Ca5(PO4)3(OH), tab sis nws feem ntau yog sau Ca10(PO4)6(OH)2 los qhia tias cov siv lead ua cell muaj ob qhov chaw.Hydroxyapatiteyog hydroxyl endmember ntawm complex apatite pawg.Ntshiabhydroxyapatite hmoovyog dawb.Ib txwm tshwm sim apatites tuaj yeem, txawm li cas los xij, kuj muaj xim av, daj, lossis ntsuab xim, piv rau cov xim ntawm cov hniav fluorosis.
Txog li 50% los ntawm ntim thiab 70% los ntawm qhov hnyav ntawm tib neeg cov pob txha yog ib daim ntawv hloov kho ntawm hydroxyapatite, hu ua pob txha ntxhia.Carbonated calcium-deficient hydroxyapatite yog cov ntxhia tseem ceeb ntawm cov hniav enamel thiab dentin.Hydroxyapatite crystals kuj pom nyob rau hauv cov calcifications me me, nyob rau hauv lub caj pas pineal thiab lwm yam qauv, hu ua corpora arenacea los yog ' hlwb xuab zeb'.
Daim ntawv thov
1. Hydroxyapatite muaj nyob rau hauv cov pob txha thiab cov hniav;pob txha yog tsim los ntawm HA crystals interspersed nyob rau hauv ib tug collagen matrix - 65 mus rau 70% ntawm cov pob txha loj yog HA.Ib yam li HA yog 70 txog 80% ntawm qhov loj ntawm dentin thiab enamel hauv cov hniav.Nyob rau hauv enamel, lub matrix rau HA yog tsim los ntawm amelogenins thiab enamelins es tsis txhob ntawm collagen.
Hydroxylapatite deposits nyob rau hauv tendons nyob ib ncig ntawm cov pob qij txha ua rau cov mob calcific tendinitis.
2. HA tau siv ntau zuj zus los uapob txha grafting cov ntaub ntawvnrog rau kev kho hniav prosthetics thiab kho.Qee qhov kev cog qoob loo, xws li kev hloov lub duav, kev cog hniav thiab kev cog pob txha, yog coated nrog HA.Raws li cov neeg tawg rog ntawm hydroxyapatite in-vivo, nyob ib ncig ntawm 10 wt% ib xyoos twg, yog qhov qis dua qhov kev loj hlob ntawm cov pob txha tshiab, hauv nws txoj kev siv los ua cov khoom siv pob txha hloov, txoj hauv kev tau nrhiav los txhim kho nws cov solubility npaum li cas thiab yog li txhawb nqa bioactivity zoo dua.
3. Microcrystalline hydroxyapatite (MH) yog kev lag luam raws li "pob txha tsim" ntxiv nrog kev nqus zoo dua hauv kev sib piv rau calcium.
