Hydrogen peroxide yog qhov ua tau substrate ntawm enzyme peroxidase . Nws yog vim rau qhov tseeb tias txhua yam tshuaj lom neeg cuam tshuam nrog hydrogen peroxide, yog muaj peev xwm rau yuav catalyzed los ntawm peroxidase.
Ua kom pom qhov no, lub substrate ntawm enzyme peroxidase yog dab tsi?
Rau ntau ntawm cov no cov enzymes qhov zoo tshaj plaws substrate yog hydrogen peroxide, tab sis lwm tus muaj zog dua nrog cov organic hydroperoxides xws li lipid peroxides. Peroxidases tuaj yeem muaj heme cofactor hauv lawv qhov chaw nquag, lossis hloov redox-active cysteine lossis selenocysteine seem.
Ib qho ntxiv, qhov twg pom peroxidase hauv tib neeg? Peroxidase kev ua 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 los ntawm polymorphonuclear leukocytes (myeloperoxidase; MPO) los yog tej zaum eosinophil (eosinophil). peroxidase ; PEB).
Hauv kev hais txog qhov no, ua li cas peroxidase enzymes ua haujlwm?
Peroxidase yog ib enzyme pom muaj ntau yam kab mob, los ntawm cov nroj tsuag rau tib neeg mus rau cov kab mob. Nws muaj nuj nqi yog txhawm rau rhuav tshem 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 muaj tshuaj lom yog dab tsi ua rau hydrogen peroxide pab tau hauv cov khoom siv pab thawj zaug.
Peroxidase test yog dab tsi?
Thyroid Kev kuaj peroxidase yog a xeem uas ntsuas cov qib ntawm cov tshuaj tiv thaiv kab mob uas raug coj tawm tsam cov thyroid peroxidase (TSO). Autoantibodies rau thyroid peroxidase (TPOAb) yog tsim nyob rau hauv lub cev. Lub xub ntiag ntawm TPOAb hauv cov ntshav qhia txog kev tawm tsam ua ntej ntawm cov thyroid cov ntaub so ntswg los ntawm lub cev tiv thaiv kab mob.

Koj paub li cas yog tias koj muaj chiggers hauv koj lub tsev?
Cov cim thiab tsos mob ntawm tus chigger tom yog dab tsi? Tshaj tawm khaus yog cov tsos mob tshwm sim tshaj plaws. Qhov chaw ntawm qhov tom tuaj yeem ua rau liab, tiaj, lossis tsa; qee zaum nws zoo li pustule lossis blister. Qhov khaus yog vim muaj cov stylostome thiab feem ntau yog khaus tshaj li ntawm 1-2 hnub tom qab tom

Ua li cas koj thiaj paub yog tias koj ob leeg sib koom ua ke hauv koj lub pinky?
Kom paub yog tias koj ob leeg sib koom ua ke, uas tseem hu ua "hypermobility", so koj lub xib teg thiab lub hauv pliaj ntawm lub tiaj tiaj, khoov koj lub luj tshib ntawm 90-degree lub kaum ntse ntse. Tom ntej no, coj koj txhais tes thiab tsa koj tus ntiv tes pinky rov qab rau koj lub cev. Yog tias nws mus tshaj 90 degrees, koj cov ntiv tes ntawm tes muaj hypermobility
Koj yuav paub li cas yog tias koj muaj kev ntxhov siab tawg hauv koj lub duav?
Feem ntau cov neeg mob uas muaj kev ntxhov siab ntawm lub duav ntawm lub duav hnov mob nyob rau hauv pem hauv ntej ntawm puab puab tais thaum sawv thiab txav mus. So feem ntau ua rau qhov mob ploj mus. Cov neeg mob tuaj yeem limp. Kev ua haujlwm hnyav, xws li khiav thiab nce ntaiv, yuav mob heev uas tus neeg mob yuav tsum tsis txhob ua lawv
