Qhov sib txawv tseem ceeb ntawm cov tshuaj tiv thaiv enzymatic thiab nonenzymatic yog cov tshuaj lom neeg lom neeg (enzymes) catalysts enzymatic cov tshuaj tiv thaiv thaum cov tshuaj catalysts catalyze qee cov tshuaj tiv thaiv nonenzymatic thaum lwm cov tshuaj tiv thaiv nonenzymatic tsis xav tau cov catalyst rau catalyzation. Yog li ntawd, cov tshuaj tiv thaiv enzymatic tsuas yog cov tshuaj lom neeg hauv cov xwm txheej, tab sis cov tshuaj tsis muaj zog tuaj yeem yog cov tshuaj lom neeg lossis tshuaj lom neeg hauv cov xwm txheej.
Enzymes yog cov khoom siv roj ntsha uas poob rau hauv qeb ntawm cov proteins tertiary. Yog li, cov enzymes no muaj cov qauv nyuaj. Feem ntau, tag nrho cov tshuaj tiv thaiv tuaj yeem muab tso rau hauv ob pawg: cov tshuaj tiv thaiv enzymatic lossis cov tshuaj tiv thaiv nonenzymatic raws li kev koom tes ntawm cov enzyme hauv catalysis ntawm cov tshuaj tiv thaiv.
Dab tsi yog Enzymatic Reaction?
Cov enzymes yog cov tshuaj lom neeg lom neeg uas tuaj yeem txo qhov ua kom lub zog ntawm cov tshuaj lom neeg lom. Tsis tas li ntawd, cov tshuaj tiv thaiv enzymatic yog cov tshuaj lom neeg lom neeg uas cov enzymes koom nrog hauv lawv cov catalysis. Lub zog ua kom muaj zog yog lub zog teeb meem uas cov reactants yuav tsum tau kov yeej thiaj li tau txais cov khoom ntawm cov tshuaj tiv thaiv. Thaum lub zog ua kom lub zog enzymes txo qhov kev ua kom lub zog, nws yog qhov peb hu ua catalysis. Yog li ntawd, enzymes muaj txiaj ntsig zoo hauv kev nce cov tshuaj tiv thaiv ntawm cov tshuaj lom neeg muaj txiaj ntsig thiab ua rau lawv nce qib los muab cov khoom lag luam.
Ntxiv mus, enzymes muaj qhov chaw tshwj xeeb ntawm lawv qhov chaw uas paub tias yog qhov chaw nquag. Cov txheej txheem ntawm cov tshuaj tiv thaiv enzymatic suav nrog kev khi ntawm cov tshuaj reactant rau ntawm qhov chaw nquag ua raws li kev nce qib ntawm cov tshuaj tiv thaiv. Thaum kawg ntawm kev ua tiav cov tshuaj tiv thaiv, cov khoom raug tso tawm los ntawm qhov chaw nquag.
Nonenzymatic Reaction yog dab tsi?
Nonenzymatic cov tshuaj tiv thaiv yog cov tshuaj lom neeg lossis tshuaj lom neeg uas, yog tias muaj cov catalyst, nws dhau los ua cov tshuaj catalyst. Qee cov tshuaj tiv thaiv tsis xav tau cov catalyst rau catalyzation. Qhov ntawd yog vim tias cov tshuaj tiv thaiv no muaj lub zog ua kom tsis muaj zog uas tsis cuam tshuam rau cov tshuaj tiv thaiv.
Daim duab 01: Browning hauv Banana
Ib qho piv txwv zoo ntawm hom tshuaj tiv thaiv no yog nonenzymatic browning hauv zaub mov. Browning yog txheej txheem ntawm tig cov khoom noj rau hauv xim av. Qhov ntawd tshwm sim vim muaj tshuaj lom neeg tshwm sim ntawm cov khoom noj. Browning tshwm sim nyob rau hauv ob txoj kev; Lawv yog enzymatic thiab nonenzymatic browning. Nyob ntawd, lub nonenzymatic browning suav nrog kev tsim cov xim xim av xim ntawm cov khoom noj uas tsis muaj kev ua haujlwm ntawm enzymes. Muaj ob hom caramelization thiab Millard cov tshuaj tiv thaiv. Caramelization cuam tshuam nrog pyrolysis ntawm qab zib tsim cov caramel tsw. Cov tshuaj tiv thaiv Millard suav nrog cov tshuaj tiv thaiv ntawm ib pawg amine thiab pawg carbonyl nyob rau hauv lub xub ntiag ntawm tshav kub ua Melanoidins.
Qhov txawv ntawm Enzymatic thiab Nonenzymatic Reaction yog dab tsi?
Cov tshuaj tiv thaiv Enzymatic yog cov tshuaj lom neeg lom neeg uas cov enzymes koom nrog hauv lawv cov catalysis. Cov tshuaj tiv thaiv nonenzymatic yog cov tshuaj lom neeg lossis tshuaj lom neeg uas, yog tias muaj cov catalyst, nws yog cov tshuaj catalyst. Yog li cov tshuaj tiv thaiv enzymatic tsuas yog cov tshuaj lom neeg hauv cov xwm txheej xwb, tab sis cov tshuaj tsis yog tshuaj lom neeg tuaj yeem yog cov tshuaj lom neeg lossis tshuaj lom neeg hauv cov xwm txheej.
Tsis tas li ntawd, enzymes catalyze hauv cov tshuaj tiv thaiv enzymatic, tab sis cov enzymes tsis koom nrog cov txheej txheem catalysis hauv cov tshuaj tiv thaiv nonenzymatic.
Summary – Enzymatic vs Nonenzymatic Reaction
Txhua cov tshuaj lom neeg thiab tshuaj lom neeg poob rau hauv ob pawg xws li cov tshuaj tiv thaiv enzymatic thiab nonenzymatic. Qhov txawv ntawm cov tshuaj tiv thaiv enzymatic thiab nonenzymatic yog cov tshuaj lom neeg catalysts (enzymes) catalyze enzymatic cov tshuaj tiv thaiv thaum qee cov tshuaj tiv thaiv nonenzymatic koom nrog cov tshuaj catalysts thaum qee qhov tsis koom nrog cov catalyst.
