Peroxidase yog ib qho enzyme pom nyob rau hauv ntau yam kab mob, los ntawm cov nroj tsuag mus rau tib neeg mus rau cov kab mob. Nws txoj haujlwm yog ua kom tawg hydrogen peroxide (H2O2), uas yog ib qho ntawm cov co toxins uas ua los ntawm kev siv oxygen rau kev ua pa. (Qhov tseeb tias nws yog tshuaj lom yog dab tsi ua hydrogen peroxide pab tau rau hauv cov khoom siv pab thawj zaug.

Ib yam li ib tug yuav nug, dab tsi cuam tshuam rau kev ua haujlwm peroxidase?

Hauv qhov kev sim no peb yuav ntsuas qhov cuam tshuam ntawm hydrogen peroxidase ntawm peb qhov chaw ib puag ncig, kub , pH, thiab enzyme concentration qib.

Tsis tas li ntawd, dab tsi tshwm sim yog catalyzed los ntawm peroxidase? Peroxidase reacts los ntawm cov txheej txheem zoo ib yam li catalase, tab sis cov tshuaj tiv thaiv catalyzed yog cov oxidation ntawm ntau yam ntawm cov organic thiab inorganic substrates los ntawm hydrogen peroxide (Reaction 5.83).

Ntxiv mus, qhov twg yog peroxidase enzyme pom?

Peroxidase kev ua si yog pom nyob rau hauv exocrine secretions xws li mis nyuj, kua muag, thiab qaub ncaug, nrog rau cov kua hauv qhov chaw mos (Table 1), feem ntau muab tau los ntawm cov enzymes synthesized nyob rau hauv cov qog, tab sis ib co kev ua derived los ntawm polymorphonuclear leukocytes (myeloperoxidase; MPO) los yog tej zaum eosinophils (eosinophil). peroxidase ; EPO).

Yuav ua li cas peroxidase rhuav tshem hydrogen peroxide?

Cov peroxidase enzyme catalyzes decomposition ntawm hydrogen peroxide rau hauv dej thiab molecular oxygen (saib daim duab). Catalase yog ib qho enzyme uas muaj hem. Yog li, ntxiv rau cov protein ib feem ntawm cov molecule, lub enzyme muaj ib feem uas tsis yog protein, uas yog ib tug derivative ntawm heam thiab muaj xws li cov hlau hlau.
