Nws muaj plaub pawg porphyrin heme (hlau) uas tso cai rau cov enzyme ua rau cov tshuaj hydrogen peroxide. Catalase tau pom thawj zaug hauv xyoo 1818 thaum Louis Jacques Thщnard, leej twg nrhiav pom H2O2 (hydrogen peroxide), qhia tias nws tawg yog tshwm sim los ntawm ib yam khoom tsis paub.
pom catalase nyob qhov twg?
Nyob rau hauv cov ntaub ntawv no oxygen yog generated thaum hydrogen peroxide tawg mus rau hauv oxygen thiab dej ntawm kev sib cuag nrog catalase, ib tug enzyme pom nyob rau hauv liver.
Kev ntsuas catalase yog dab tsi?
Kev kuaj catalase yog qhov tshwj xeeb ntsuas tseem ceeb siv los txiav txim seb tus kab mob gram-zoo cocci yog staphylococci lossis streptococci . Catalase yog ib qho enzyme uas hloov cov hydrogen peroxide rau dej thiab cov pa oxygen. Qhov kev xeem no yooj yim ua; Cov kab mob tsuas yog sib xyaw nrog H2O2.
Lwm lub npe ntawm catalase yog dab tsi?
3 Peroxidases . Peroxidases, tseem hu ua catalases, kuj yog chav kawm oxidoreductase ntawm cov enzymes, uas ua rau cov tshuaj tiv thaiv oxidoreduction. Lub peroxidase enzyme catalyzes decomposition ntawm hydrogen peroxide rau hauv dej thiab molecular oxygen (saib daim duab). Catalase yog ib qho enzyme uas muaj haem.
Lub hauv paus ntsiab lus ntawm kev kuaj catalase yog dab tsi?
PRINCIPLE: Kev tawg ntawm hydrogen peroxide rau hauv oxygen thiab dej yog kho los ntawm enzyme catalase. Thaum ib qho me me ntawm cov kab mob uas tsim catalase tau nkag mus rau hauv hydrogen peroxide, saiKev nthuav dav ntawm cov npuas ntawm cov pa oxygen, cov khoom lag luam gaseous ntawm cov enzyme kev ua, yog tsim.
