Covcov enzymes yog cov protein uas ua zoo li catalysts, yog ua kom cov tshuaj lom sai yam tsis tau siv lossis dhau los ua ib feem ntawm cov khoom ntawm qhov ntawd cov tshuaj tiv thaiv. Txhua qhov kev tawm tsam uas tshwm sim hauv lub cev tau kho los ntawm cov enzymes, yog li nws pom tseeb tias cov enzymes muaj ntau yam kev ua haujlwm hauv cov kab mob muaj sia.
Ntawm cov haujlwm ntawm cov enzymes yog qhov ntawmtxhawb kev zom thiab nqus cov as -ham, los ntawm cov zaub mov uas tau noj: zom zom zom zom zom cov protein ntau, carbohydrates thiab cov rog hauv cov khoom sib luag.
Hauv qhov kev nkag siab no nws tau hais tias cov enzymes muaj txiaj ntsig zoo rau thaum mob plab, roj thiab feem ntau hnyav heev. Lawv kuj tsim cov inhibition ntawm inflammatory dab thiab nyiam qhov ntaus rov qab, nrog rau kev pab tshem tawm cov co toxins thiab ua kom lub cev tsis muaj zog.
Cov xwm txheej rau kev ua haujlwm enzyme
Txawm li cas los xij, kev ua haujlwm enzyme tau ua nrog kev ua haujlwm sib txawv nyob ntawm qee yam mob uas yuav muaj nyob hauv lub cev. Piv txwv li, a siab dua substrate concentration sau ib siab enzyme ntau dua tus nqi uas cov tshuaj tiv thaiv enzymatic tshwm sim nce, txawm tias mus txog qee qhov txwv.
Ntawm qhov tod tes, nce 10 ° C ob npaug ntawm qhov nrawm ntawm cov tshuaj tiv thaiv, tab sis thaum mus txog qhov txwv tsis pub dhau, cov cua sov ua rau tsis muaj txiaj ntsig nrog kev ua haujlwm enzymatic. Tsis tas li ntawd, cov qhov zoo tshaj plaws pH ntawm kev ua haujlwm enzymatic yog 7 (tshwj tsis yog hauv plab zom mov, nyob hauv cov ntsiab lus kua qaub plab).
Kev faib tawm
Kev faib tawm uas ua los ntawm cov enzymes sib txawv ntawm cov uas tshuaj xyuas lawv cov nyom, cov uas tshuaj xyuas lawv cov cofactors lossis cov uas koom nrog hauv kev ua haujlwm enzymatic:
Cov hydrolases yog cov uas catalyze hydrolysis tshua, thaum lub isomerases lus yog cov uas catalyze tshua uas ib isomer hloov pauv mus rau lwm qhov. Cov pab koomtes catalyze kev khi ntawm cov molecules, thaum lias lawv ua raws li qhov xav tau ntawm kev ntxiv lossis tshem tawm cov ntawv cog lus. Cov oxidoreductases catalyze oxidation-txo cov tshuaj tiv thaiv (ua kom yooj yim hloov pauv hluav taws xob) thiab tansferases lus lawv catalyze kev hloov pauv ntawm ib pab pawg los ntawm ib yam khoom mus rau lwm qhov.
Enzymes hauv cov txheej txheem kev lag luam
Muaj ntau cov txheej txheem kev lag luam uas yog khi rau kev ua haujlwm ib txwm muaj ntawm cov enzymes. Cov cawv cawv thiab lwm yam khoom lag luam npaj rau noj, thaum ntau qhov kev cuam tshuam uas cuam tshuam hauv ntiaj teb xws li kev tsim kho yog nyob ntawm lawv.
Qee zaum cov Enzymes siv rau lub hom phiaj kho mob, npaj kho thaj chaw ntawm qhov mob hauv zos.
Nov yog qee qhov piv txwv ntawm cov hom enzymes nrog qee qhov ntawm lawv lub luag haujlwm, lom lossis tsim khoom.
Piv txwv ntawm cov enzymes thiab lawv lub luag haujlwm
- Trypsin: Nws ua txhaum cov peptide bonds uas nyob ib sab rau arginine lossis lysine.
- Lactase: Siv hauv kev lag luam mis nyuj, nws tiv thaiv crystallization ntawm mis nyuj khov
- Gastrine: Ua thiab zais cov kua qaub hydrochloric, thaum txhawb kev mob plab.
- Dipeptidase: Tus tsim khoom ntawm ob qho amino acids.
- Chymosin: Coagulates cov protein hauv cov cheese.
- Lipase: cov Muab cov roj fatty acids, muab tias nws ua haujlwm hauv ib puag ncig alkaline, nrog yav dhau los ua ntawm cov ntsev ntsev.
- Secretin: Cov Nws zais cov dej thiab sodium bicarbonate, ntxiv rau inhibiting plab zom mov.
- Glucose isomerases: Tso cai siv cov fructose syrups siab hauv kev tsim cov khoom qab zib.
- Papain: Hauv lub npias, nws tau siv los ua kua malt muab tshuaj txhuam.
- Lub plab vasoactive peptide: Ua kom cov ntshav ntws ntau ntxiv thiab zais cov kua dej hauv lub cev.
- Sucaraa: Ua cov piam thaj thiab fructose.
- Fiscina: Qhov tseem ceeb hauv kev ua cov nqaij.
- Carboxypeptidase: Sib cais davhlau ya nyob twg carboxyamino acids.
- Bromelain: Nws koom nrog hauv kev tsim cov hydrolysates.
- Deoxyribonuclease: Nws tsim cov nucleotides, nrog cov txheej txheem ntawm DNA.
- Encephalin: Kev txwv tsis pub tso tawm ntawm cov txiav ua kab mob pancreatic enzymes thiab ntawm lub zog kev xav.
- Somatostatin: Inhibits qhov tso pa tawm ntawm hydrochloric acid.
- Amylase: Muab cov piam thaj hauv plab thiab txiav txiav, yog tias nws ua haujlwm hauv ib puag ncig acidic.
- Lipoxidase: kev kho mob Hauv kev lag luam qhob cij, nws txhim kho nws cov txiaj ntsig zoo thiab ua kom muaj cov qhob cij dawb heev.
- Pepsin: Nws tsim peptides thiab amino acids hauv plab, qhov nruab nrab acidic heev.
- Ribonuclease: Ua cov nucleotides, nrog RNA substrate.
- Glucagon tag nrho: Txwv tsis pub txav mus los thiab tso zis.
- Pectinases: Hauv kev lag luam dej haus, nws txhim kho qhov kev piav qhia thiab tshem tawm ntawm cov kua txiv.
- Tannasa: Hloov cov piam thaj mus rau fructose, ntxiv rau tiv thaiv kom xim av thiab tsis hnov tsw hauv qee cov dej haus.
- Ptyalin: Muab monosaccharides thiab disaccharides, yog tias nws ua nyob rau ib puag ncig nruab nrab alkaline.
