Dehydrogenases yog ib pawg ntawm cov tshuaj lom neeg lom neeg (enzymes) uas nruab nrab hauv cov tshuaj lom neeg biochemical tshem tawm hydrogen atoms [H] es tsis txhob oxygen [O] hauv nws cov tshuaj tiv thaiv oxido-txo. Nws yog ntau yam enzyme nyob rau hauv txoj kev ua pa ntawm txoj kev ua pa los yog cov hlau hloov hluav taws xob.
Y Yuav ua li cas hom enzyme yog dehydrogenase?
A dehydrogenase yog ib qho enzyme uas koom nrog pawg ntawm oxidoreductases uas oxidizes lub substrate los ntawm kev txo cov electron txais, feem ntau NAD+ / NADP+ lossis flavin coenzyme xws li FAD lossis FMN.
Dab tsi yog dehydrogenase kev ua haujlwm muab nws qhov tseem ceeb?
Dehydrogenases ua lub luag haujlwm tseem ceeb hauv kev lom oxidation ntawm av organic teeb meem (OM) los ntawm kev hloov hydrogen los ntawm cov organic substrates rau inorganic txais(Zhang li al., 2010). … Thoob plaws hauv qhov hais txog co-enzymes hydrogen atoms koom nrog hauv cov txheej txheem txo qis ntawm biosynthesis.
Lub luag haujlwm ntawm dehydrogenase hauv glycolysis yog dab tsi?
Dehydrogenase enzymes tshem tawm hydrogen ions thiab electrons los ntawm nruab nrab ntawm lub voj voog no, uas tau dhau mus rau coenzyme NAD (ua NADH). Cov hydrogen ions thiab electrons raug xa mus rau electron thauj saw ntawm lub puab mitochondrial membrane. Qhov no tshwm sim hauv ob qho tib si glycolysis thiab citric acid voj voog.
Lub luag haujlwm ntawm dehydrogenase enzyme Dab tsi yog lub luag haujlwm dab tsi ua cov enzymes ua si hauv oxidation txo redoxkev tshwm sim?
Dehydrogenase (DHO) yog ib qho ntawm cov enzyme feem ntau uas yog qhov tseem ceeb hauv cov tshuaj tiv thaiv oxidation. Qhov enzyme no oxidizes nws cov substrate tshwj xeeb los ntawm cov tshuaj tiv thaiv redox uas ib lossis ntau dua hydrides (H -) raug xa mus rau ib qho khoom siv hluav taws xob.
