Dehydrogenases yog subclass ntawm cov enzymes hu ua "oxidoreductases." Oxidoreductases, feem ntau, catalyze oxidation thiab txo cov tshuaj tiv thaiv. Feem ntau oxidoreductase enzymes yog dehydrogenases , txawm hais tias reductases kuj muaj ntau.
Ib sab ntawm no, dab tsi yog hydrolase enzymes?
Hydrolase . Hydrolases yog hydrolytic cov enzymes , biochemical catalysts uas siv dej txhawm rau txhawm rau cov tshuaj lom neeg, feem ntau faib cov molecule loj rau hauv ob lub me me. Piv txwv li hydrolases muaj xws li esterases, proteases, glycosidases, nucleosidases, thiab lipases.
Qhov thib ob, yuav ua li cas yog tias tsis muaj cawv dehydrogenase? Cov Cawv dehydrogenase (ADH) rov ethanol rau hauv acetaldehyde thiab acetaldehyde yog lom heev thiab thiab ua rau muaj kev phiv tsis zoo heev. Yog ADH enzyme tsis ua haujlwm tag nrho, ADH yuav tsis tuaj yeem tawg ethanol mus rau acetaldehyde.
Dab tsi yog lub luag haujlwm ntawm dehydrogenase hauv kev ua haujlwm photosynthesis?
NADP-dependent malate dehydrogenase (NADP-MDH) yog chloroplast enzyme muaj nyob rau hauv ntsuab algae thiab ntau hom av nroj tsuag. Lub enzyme catalyzes txo qis ntawm oxaloacetate rau malate siv NADPH raws li reductant nyob rau hauv cov tshuaj tiv thaiv uas nruj me ntsis yuav tsum tau lub teeb-kiv los ntawm Fdx / Trx system.
Puas yog cawv dehydrogenase yog cov protein?
ALCOHOL DEHYDROGENASES Lawv yog dimeric cov protein , nrog txhua subunit khi ob Zn2+ ions, tsuas yog ib qho uas yog catalytically nquag. Qhov no catalytic Zn2+ ion tau hloov pauv tetrahedral geometry, sib koom ua ke rau ib histidine thiab ob cysteine seem.

Pyruvate dehydrogenase ua dab tsi?
Pyruvate dehydrogenase (PDH) yog lub ntsiab lus hloov pauv hauv kev tswj hwm kev zom zaub mov kom zoo ntawm cov piam thaj thiab FA oxidation. Li no, PDH hloov pauv pyruvate mus rau acetyl-coA, thiab yog li ua rau kom muaj kev nkag los ntawm acetyl-coA los ntawm glycolysis mus rau hauv TCA voj voog
Puas yog kev khuv leej kev qaug zog yog kev puas siab puas ntsws?
Cov kws tshaj lij uas ua haujlwm hauv kev puas siab puas ntsws muaj kev pheej hmoo ntawm kev tsim kev puas siab puas ntsws rau lawv tus kheej. Lo lus "kev khuv leej neeg qaug zog" tau siv los piav txog qhov tsis zoo ntawm kev ua haujlwm hauv ib puag ncig kev puas siab puas ntsws rau tus neeg lub peev xwm kom muaj kev khuv leej rau lwm tus
Puas yog ntau tus cwj pwm tsis zoo yog kev puas siab puas ntsws?
Differential Diagnosis: Kev nyuaj siab loj heev
Puas yog tus mob schizophrenia yog ib qho kev puas siab puas ntsws?
Pov thawj tias Schizophrenia yog Kab Mob Hlwb. Cov ntaub ntawv los ntawm kev tshawb fawb tshawb fawb ua pov thawj tias tus mob schizophrenia yog ib qho kab mob ntawm lub hlwb, ib yam li Alzheimer's Disease thiab Bipolar Disorder. Schizophrenia tam sim no paub tias yog ib feem los ntawm cov noob caj noob ces thiab yuav tau txais txiaj ntsig
Puas yog germaphobe puas yog kev puas siab puas ntsws?
Kev cai huv huv Germaphobes lub neej. Germaphobes muaj kev nyiam huv nrog kev huv thiab xav tias yuav tsum tau ntxuav ntau dhau, tab sis lawv tau raug kev txom nyem tiag tiag los ntawm kev tsis quav ntsej-yuam kev. Tib neeg feem ntau muaj ntau hom ntaub ntawv ntawm OCD
