Qhov txawv ntawm esterase thiab lipase yog tias esterase yog ib qho enzyme uas hydrolyzes dej-soluble luv acyl saw esters thaum lub lipase yog ib qho enzyme uas hydrolyzes dej-insoluble ntev saw triacylglycerols.
Y Hydrolases yog enzymes uas catalyze qhov tseem ceeb, hydrolysis ntawm cov organic tebchaw. Nyob rau hauv lub tshav pob ntawm lipids thiab rog digestion thiab hydrolysis, muaj ob lub ntsiab ntawm hydrolases koom nrog. Lawv yog esterases thiab lipases. Esterase yog ib qho enzyme uas catalyzes hydrolysis ntawm ester compounds. Hauv kev sib piv, lipase belongs rau ib pawg ntawm esterase. Nws catalyzes hydrolysis ntawm lipids, tshwj xeeb tshaj yog thaum digestive. Esterases yog cov dej-soluble tshuaj whereas lipases yog dej-insoluble thiab hnyav aggregate nyob rau hauv dej.
Esterase yog dab tsi?
Esterase yog hom hydrolase uas tuaj yeem cleave thiab tsim ester bonds. Yog li, esterase tuaj yeem tshem tawm ester daim ntawv cog lus ua rau muaj cawv thiab kua qaub nyob rau hauv cov dej. Tshwj xeeb tshaj yog esterases hydrolyze luv-chain fatty acids. Lawv yog cov stereospecific heev thiab substrate-specific enzymes. Ntxiv mus, lawv feem ntau koom nrog txoj hauv kev catabolic thiab ultra-purification ntawm cais cov lipid compounds. Raws li, esterases feem ntau muaj nyob rau hauv cov tsiaj, nroj tsuag thiab kab mob. Lub npe ntawm esterase tshwm sim raws li lawv cov substrates. Piv txwv li, acetylcholine esterase yuav hydrolyze tsuas yog acetylcholine thiab tsis muaj lwm yam substrate.
Daim duab 01: Esterase
Tsis tas li ntawd, ib qho esterase yog dej soluble thiab tsawg soluble hauv cov kuab tshuaj organic. Yog li ntawd, esterases muaj ntau polar amino acids nyob rau hauv lawv lub koom haum. Yog li, lawv tsis muaj zog tiv thaiv cov kab mob ntev fatty acids xws li triacylglycerols. Yog li, hydrolysis ntawm cov saw ntev fatty acids yuav tsum tau hloov enzyme xws li lipase.
Lipase yog dab tsi?
Lipase yog dej-insoluble lipid hydrolytic enzyme. Yog li ntawd, lipase tsim aggregate nyob rau hauv aqueous daws. Nws yog qhov feem ntau lipid hydrolytic enzyme nyob rau hauv tag nrho cov kab mob. Hauv qib siab dua eukaryotes, lipase muaj nyob rau hauv salivary lipase, plab lipase, thiab plab hnyuv lipase.
Daim duab 02: Lipase
Tsis tas li ntawd, lipases yog ib feem ntawm esterases. Txawm li cas los xij, tsis zoo li esterase, lipase yog soluble hauv cov kuab tshuaj organic. Yog li ntawd, lawv tau nkag siab nrog cov loj tsis muaj polar fatty acid chains thiab hydrolyze lawv. Ib yam li ntawd, cov saw ntev triglycerides tau txais hydrolysis ntawm lipases. Txawm li cas los xij, enzyme lipase yog dav dav thiab tsis tshua muaj substrate. Tsis tas li ntawd, lawv muaj ntau hydrophobic amino acids uas ua rau lawv tsis muaj polar ntau dua nyob rau hauv qhov.
Dab tsi yog qhov zoo sib xws ntawm Esterase thiab Lipase?
- Esterase thiab lipase muaj nyob hauv txhua lub tebchaws suav nrog tsiaj txhu, nroj tsuag thiab kab mob.
- Ob leeg muaj qhov dav dav substrate.
- Tsis tas li, ob qho tib si esterase thiab lipase ua raws li fatty acids.
- Ntxiv mus, ob leeg koom nrog cov tshuaj tiv thaiv hydrolysis.
- Dhau li ntawd, lawv yog cov proteins thiab tej zaum yuav los yog tsis muaj cov protein sib tshooj lossis cov protein ntau.
Qhov txawv ntawm Esterase thiab Lipase yog dab tsi?
Esterase thiab lipase yog ob lub enzymes uas tseem ceeb hauv lipid hydrolysis thiab digestion. Qhov tseeb, lipase yog ib qho enzyme uas belongs rau ib pawg ntawm esterases. Qhov sib txawv tseem ceeb ntawm esterase thiab lipase yog tias esterase catalyzes hydrolysis ntawm luv-chain fatty acids thaum lub lipase catalyzes hydrolysis ntawm ntev saw fatty acids. Tsis tas li ntawd, esterase feem ntau ua rau cov dej-soluble substrates thaum lub lipase feem ntau ua rau dej-insoluble substrates. Yog li, qhov no kuj yog qhov sib txawv ntawm esterase thiab lipase.
Tsis tas li, qhov sib txawv ntxiv ntawm esterase thiab lipase yog tias esterase muaj tsawg dua hydrophobic amino acids thaum lipase muaj ntau cov hydrophobic amino acids. Yog li, esterases yog dej soluble thaum lipases tsis soluble hauv dej. Tsis tas li ntawd, esterases qhia qhov tshwj xeeb ntawm cov substrate thiab siab stereospecificity piv rau lipases. Yog li, nws yog lwm qhov sib txawv ntawm esterase thiab lipase.
Cov hauv qab no infographic ntawm qhov sib txawv ntawm esterase thiab lipase qhia cov ntaub ntawv ntau ntxiv ntawm qhov sib txawv no.
Summary – Esterase vs Lipase
Ob leeg esterase thiab lipase muaj nyob hauv tsev neeg hydrolase, thiab lawv hydrolyze fatty acids. Qhov sib txawv tseem ceeb ntawm esterase thiab lipase nyob ntawm lawv cov solubility thiab hom fatty acid lawv hydrolyze. Esterase yog soluble hauv dej. Hauv kev sib piv, lipase tsis soluble hauv dej. Ntxiv mus, esterase hydrolyzes luv-chain fatty acids, whereas lipase hydrolyzes ntev saw fatty acids. Ob lub enzymes muaj nyob rau hauv tag nrho cov kab mob thiab yog ib qho tseem ceeb nyob rau hauv lub digestive txheej txheem ntawm lipids. Li no, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm esterase thiab lipase.
