Cyanide yog ib qho piv txwv ntawm tsis sib tw inhibitor. Cyanide khi rau qhov kawg enzyme nyob rau hauv lub electron thauj saw, thiab tiv thaiv no enzyme los ntawm catalysing cov tshuaj tiv thaiv los ntawm oxygen rau dej.
Puas yog cyanide sib tw lossis tsis sib tw inhibitor?
Cyanide cuam tshuam nrog ntau dua 40 metalloenzymes, tab sis nws qhov ua rau tuag taus yog tsis sib tw inhibition ntawm cytochrome c oxidase, nres cellular respiration thiab ua rau hypoxic anoxia.
Puas yog cyanide yog qhov sib tw inhibitor ntawm oxygen?
3. CO yog nruj me ntsis kev sib tw, azide thiab formate yog uncompetitive, thiab cyanide thiab sulfide yog tsis sib tw inhibitors rau oxygen.
Cov piv txwv ntawm kev sib tw inhibitors yog dab tsi?
Ib qho piv txwv ntawm kev sib tw inhibitor yog cov tshuaj antineoplastic methotrexateMethotrexate muaj cov qauv zoo ib yam li cov vitamin folic acid (Fig. 4-5). Nws ua los ntawm inhibiting enzyme dihydrofolate reductase, tiv thaiv kev tsim dua tshiab ntawm dihydrofolate los ntawm tetrahydrofolate.
Cyanide ua haujlwm li cas los ua enzyme inhibitor?
Cyanide ua raws li kev sib tw inhibitor rau enzyme cytochrome c oxidase. Qhov no tiv thaiv cov saw hlau thauj hluav taws xob (qhov kawg ntawm kev ua pa ntawm tes) los ntawm kev ua haujlwm, txhais tau tias lub xov tooj ntawm tes tsis tuaj yeem tsim ATP rau lub zog ntxiv lawm. Cov ntaub so ntswg uas nyob ntawm ntau lub zog (CNS thiab lub siab) cuam tshuam tshwj xeeb.
