Cov ntsiab lus: Carbonic anhydrase yog ib qho enzyme uas sib npaug pH ntawm cov ntshav thiab ua rau ua pa tawm ntawm carbon dioxide. Hauv cov qe ntshav liab carbonic anhydrase catalyzes cov tshuaj tiv thaiv los hloov cov pa roj carbon dioxide rau hauv carbonic acid, uas ntxiv mus rau hauv bicarbonate ions thiab protons (H+).
Lub luag haujlwm ntawm carbonic anhydrase yog dab tsi?
Carbonic anhydrase yog ib qho enzyme uas pab hloov pauv sai ntawm carbon dioxide thiab dej rau hauv carbonic acid, protons thiab bicarbonate ions Cov enzyme no tau pom thawj zaug hauv xyoo 1933, hauv cov ntshav liab. hlwb nyuj. Txij thaum ntawd los, nws tau pom tias muaj ntau nyob rau hauv tag nrho cov ntaub so ntswg mammalian, nroj tsuag, algae thiab kab mob.
carbonic acid tawg ua dab tsi?
Thaum cov pa roj carbon dioxide nkag mus rau hauv cov ntshav, nws ua ke nrog dej los tsim carbonic acid, uas dissociates rau hydrogen ions (H+) thiab bicarbonate ions (HCO.3-)..
Yuav ua li cas thaum carbonic anhydrase txo qis?
Thaum ib ntus, cov neeg uas muaj carbonic anhydrase VA deficiency muaj cov ammonia ntau dhau hauv cov ntshav (hyperammonemia), teeb meem nrog cov kua qaub-puag hauv cov ntshav (metabolic acidosis thiab ua pa alkalosis), cov piam thaj hauv cov ntshav qis (hypoglycemia), thiab txo qis kev tsim cov tshuaj hu ua bicarbonate hauv lub siab
Lub luag haujlwm ntawm carbonic anhydrase yog dab tsi hauv acid-base tshuav?
Lub enzyme tswj cov kua qaub-puag thiab pab thauj cov pa roj carbon dioxide. Carbonic anhydrase pab tswj cov kua qaub-base homeostasis, tswj pH, thiab kua dej sib npaug… Qhov tseem ceeb ntawm kev nce hauv carbon dioxide ua rau cov ntshav qis pH uas txo qis oxygen-hemoglobin khi.
