Mechanism of Action ntawm Ethylenediaminetetraacetic Acid (EDTA ACID)

Cov neeg ua haujlwm chelation ua haujlwm los ntawm kev tsim cov ntawv cog lus nrog ntau yam hlau ions, suav nrog calcium, zinc, txhuas, thiab lwm yam. Tom qab cov ntawv cog lus no tau tsim, tsim cov chelate-hlau complex uas tuaj yeem tawm ntawm lub cev. Nyob rau hauv ib txoj kev zoo sib xws, Ethylenediaminetetraacetic Acid (EDTA ACID) muaj cov txheej txheem nyuaj uas tso cai rau nws los khi ntau yam hlau. Cov molecular muaj pes tsawg leeg ntawm Ethylenediaminetetraacetic Acid (EDTA ACID) muaj ntau cov pa oxygen molecules, uas ua haujlwm pub dawb electrons thiab tsim kev sib koom ua ke nrog cov hlau ions. Thaum calcium disodium edetate khi rau cov hlau, calcium raug tshem tawm ntawm cov qauv. Cov ntawv cog lus tsim nrog cov hlau muaj zog heev thiab tiv thaiv kev cuam tshuam ntxiv los ntawm kev tshwm sim ua ntej tawm hauv lub cev.

● Absorption
Ethylenediaminetetraacetic Acid (EDTA ACID) yog nqus tau sai heev los ntawm kev nkag mus rau hauv cov hlab ntsha thiab txav mus rau hauv cov ntshav thiab cov kua nruab nrog cev. Kev tswj hwm qhov ncauj raug zam vim qis heev (tsawg dua 5%) nqus thiab ua kom muaj cov hlau lead hauv cov kab mob hauv plab.

● Kev faib tawm
Ethylenediaminetetraacetic Acid (EDTA ACID) yog muab faib thoob plaws hauv tag nrho cov khoom siv ntxiv. Hauv cov ntshav, cov molecule nyob hauv cov ntshav. Nws muaj daim ntawv ionic tiv thaiv nws los ntawm kev nkag mus rau hauv cov hlwb.

● Metabolism/Excretion
Tom qab IV kev tswj hwm, calcium Ethylenediaminetetraacetic Acid (EDTA ACID) feem ntau mus unmetabolized thiab tawm hauv nws daim ntawv tswj hwm los ntawm ob lub raum. Ib yam li ntawd, cov chelate-hlau complexes yuav tawm sai sai hauv cov zis. Ib nrab-lub neej yog nyob ib ncig ntawm 20 mus rau 60 feeb. Lub raum tuaj yeem lim tawm cov tshuaj thiab tso rau hauv tubular lumen.

Kev Koom Tes Chemistry Txoj Cai Ntawm Ethylenediaminetetraacetic Acid (EDTA ACID)

Hauv kev sib koom ua ke chemistry, EDTA4- yog ib tus tswv cuab ntawm tsev neeg aminopolycarboxylic acid ntawm ligands. EDTA4- feem ntau khi rau cov hlau cation los ntawm nws ob amines thiab plaub carboxylates, piv txwv li, nws yog ib tug hexadentate ("rau-toothed") chelate agent. Ntau ntawm cov txiaj ntsig kev sib koom ua ke tau txais octahedral geometry. Txawm hais tias muaj qhov tshwm sim me me rau nws cov ntawv thov, cov octahedral complexes yog chiral. Lub cobalt(III) anion [Co(EDTA)]- tau raug txiav mus rau hauv enantiomers.

Ntau qhov complexes ntawm EDTA4- txais yuav ntau cov qauv vim yog kev tsim ntawm ib qho kev sib txuas ntxiv rau dej, piv txwv li xya-coordinate complexes, los yog kev hloov ntawm ib tug carboxylate caj npab los ntawm dej. Cov hlau (III) complex ntawm Ethylenediaminetetraacetic Acid (EDTA ACID) yog xya-coordinate. Ethylenediaminetetraacetic Acid (EDTA ACID) tsim tshwj xeeb muaj zog complexes nrog Mn(II), Cu(II), Fe(III), Pb(II) thiab Co(III).
Ntau yam ntawm EDTA's complexes muaj feem xyuam rau nws cov ntawv thov. Ua ntej, vim nws qhov siab denticity, cov ligand no muaj kev sib raug zoo rau cov hlau cations:

[Fe(H2O)6]3+ + H4EDTA ⇌ [Fe(EDTA)]− + 6 H2O + 4 H+ Keq=1025.1

Qhov sib npaug quotient qhia tau hais tias hlau ions sib tw nrog protons rau kev khi rau Ethylenediaminetetraacetic Acid (EDTA ACID). Vim tias cov hlau ions tau nthuav dav los ntawm EDTA, lawv cov khoom catalytic feem ntau raug txwv. Thaum kawg, txij li cov complexes ntawm EDTA4- yog anionic, lawv zoo li soluble hauv dej. Vim li no, Ethylenediaminetetraacetic Acid (EDTA ACID) muaj peev xwm yaj cov hlau oxides thiab carbonates.

Cov txiaj ntsig pKa ntawm dawb Ethylenediaminetetraacetic Acid (EDTA ACID) yog 0, 1.5, 2, 2.66 (deprotonation ntawm plaub pawg carboxyl) thiab 6.16, 10.24 (deprotonation ntawm ob pawg amino).
