Qhov sib txawv tseem ceeb ntawm cov kua qaub hydrolysis thiab enzymatic hydrolysis yog cov kua qaub hydrolysis yog cov txheej txheem tshuaj, hos enzymatic hydrolysis yog cov txheej txheem biochemical.
Hydrolysis yog hais txog kev sib cais ntawm cov tshuaj sib txuas nrog kev sib ntxiv ntawm cov dej molecule. Nws tuaj yeem tshwm sim hauv ob txoj hauv kev: los ntawm kev siv tshuaj lom neeg los yog kev siv roj ntsha. Thaum nws tshwm sim tshuaj, peb hu nws acid hydrolysis thiab qhov ua rau ntawm daim ntawv cog lus cleavage yog ib hom tshuaj (ib qho acid). Txawm li cas los xij, hydrolysis los ntawm kev siv tshuaj lom neeg hu ua enzymatic hydrolysis vim tias cov nyiaj sib cais hauv cov txheej txheem no tshwm sim nyob rau hauv muaj cov enzymes.
YAcid Hydrolysis yog dab tsi?
Acid hydrolysis yog qhov sib cais ntawm cov tshuaj sib txuas hauv cov molecules los ntawm kev sib ntxiv ntawm cov dej molecule nyob rau hauv lub xub ntiag ntawm ib tug acidic nruab nrab. Txawm li cas los xij, qhov no tsis yog qhov sib ntxiv ntawm cov dej molecule; Nws tuaj yeem yog qhov sib ntxiv ntawm cov tshuaj lom neeg ntawm cov dej molecule uas ua rau cov nyiaj sib cais.
Daim duab 01: Ib qho piv txwv ntawm Acid Hydrolysis
Cov txheej txheem cleavage yog catalyzed los ntawm ib tug protic acid (ib qho kua qaub uas muaj peev xwm pub hydrogen ions). Cov tshuaj tiv thaiv acid hydrolysis yog ib hom kev hloov pauv nucleophilic. Piv txwv li, qhov sib ntxiv ntawm H + ions thiab OH- (hydroxyl ions) rau cellulose molecule tsim cov piam thaj molecules. Txawm li cas los xij, peb tsis tuaj yeem siv lo lus no rau hydration cov tshuaj tiv thaiv ntawm daim ntawv cog lus cleavage ntawm ob lossis triple bonds ntawm electrophilic ntxiv cov tshuaj tiv thaiv.
YEnzymatic Hydrolysis yog dab tsi?
Enzymatic hydrolysis yog hais txog kev sib cais ntawm cov tshuaj lom neeg hauv cov molecules los ntawm kev sib ntxiv ntawm cov dej molecule nyob rau hauv lub xub ntiag ntawm ib tug enzyme. Txawm li cas los xij, qhov no tsis yog qhov sib ntxiv ntawm cov dej molecule; Nws tuaj yeem yog qhov sib ntxiv ntawm cov tshuaj lom neeg ntawm cov dej molecule uas ua rau cov nyiaj sib cais.
Daim duab 02: Ib qho piv txwv ntawm Enzymatic Hydrolysis
Nyob rau hauv cov tshuaj tiv thaiv no, cov enzyme ua raws li cov catalyst rau cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv no tseem ceeb heev hauv kev zom zaub mov hauv peb lub cev. Nws yog cov tshuaj tiv thaiv ntau-kauj ruam nyob rau hauv uas insoluble cellulose pib tawg ntawm cov khoom-kua interface uas tsim nyob rau hauv lub plab zom mov ntawm lub synergetic kev txiav txim ntawm enzymes xws li endoglucanases. Ntxiv mus, nws muaj txiaj ntsig zoo hauv kev muab lub zog tauj dua tshiab. E.g. Cellulosic ethanol.
Qhov txawv ntawm Acid Hydrolysis thiab Enzymatic Hydrolysis yog dab tsi?
Hydrolysis, uas yog qhov sib cais ntawm cov tshuaj sib txuas hauv cov molecules, tuaj yeem tshwm sim ob txoj hauv kev ua cov txheej txheem tshuaj lom neeg thiab ua cov txheej txheem lom neeg. Cov txheej txheem tshuaj hu ua acid hydrolysis thaum txoj kev lom neeg hu ua enzymatic hydrolysis, nyob ntawm seb qhov ua rau ntawm daim ntawv cog lus cleavage. Yog li, qhov sib txawv tseem ceeb ntawm cov kua qaub hydrolysis thiab enzymatic hydrolysis yog cov kua qaub hydrolysis yog cov txheej txheem tshuaj, hos enzymatic hydrolysis yog txheej txheem biochemical. Acid hydrolysis yog qhov tseem ceeb hauv kev hloov tshuaj lom neeg xws li hloov pauv cellulose rau hauv qabzib thaum enzymatic hydrolysis tseem ceeb hauv kev zom zaub mov, muab lub zog tauj dua tshiab, thiab lwm yam.
Hauv qab infographic tabulates qhov sib txawv ntawm acid hydrolysis thiab enzymatic hydrolysis.
Summary – Acid Hydrolysis vs Enzymatic Hydrolysis
Hydrolysis yog hais txog kev sib cais ntawm cov tshuaj lom neeg hauv cov molecules. Nws tuaj yeem tshwm sim hauv ob txoj hauv kev ua cov txheej txheem tshuaj lom neeg thiab ua cov txheej txheem lom neeg. Cov txheej txheem tshuaj hu ua acid hydrolysis thaum txoj kev lom neeg muaj npe hu ua enzymatic hydrolysis, nyob ntawm qhov ua rau ntawm daim ntawv cog lus cleavage. Yog li, qhov sib txawv tseem ceeb ntawm acid hydrolysis thiab enzymatic hydrolysis yog cov kua qaub hydrolysis yog cov txheej txheem tshuaj, hos enzymatic hydrolysis yog txheej txheem biochemical.
