Lactase enzyme yog dab tsi?

Lactaseyog ib tug digestive enzyme nyob rau hauv tib neeg lub cev. Nws yog qhov tseem ceeb tshaj plaws digestive enzyme nyob rau hauv cov me nyuam mos thiab cov me nyuam yaus uas nws lub ntsiab ntawm kev noj haus yog cov kua mis / mis hmoov. Nws lub luag haujlwm tseem ceeb yog zom lactose thiab hydrolyze lactose rau hauv galactose thiab qabzib uas tuaj yeem nqus tau los ntawm tib neeg lub cev. Qhov tsis muaj lactase hauv tib neeg lub cev tuaj yeem ua rau lactose digestion thiab tsis haum rau kev nqus, thiab qee cov neeg mob muaj cov tsos mob ntawm kev zom zaub mov xws li mob plab, flatulence thiab raws plab, uas yog hu ua lactose intolerance.
Nws yog tsuas yog siv nyob rau hauv cov khoom noj siv mis nyuj siv los hloov cov kua qab zib thiab cov kua mis tsis muaj lactose rau hauv qab zib thiab ntau soluble monosaccharides; Nws txo qhov muaj peev xwm ntawm crystallization ntawm lactose nyob rau hauv cov dej khov, cov mis nyuj khov, thiab cov mis nyuj evaporated, thaum ua kom qab zib.
Secreted los ntawm txhuam ciam teb hlwb ntawm tib neeg lub plab hnyuv mucosa, nws muaj peev xwm decompose lactose nyob rau hauv cov khoom noj rau hauv qabzib thiab galactose, uas yuav absorbed thiab siv los ntawm cov hnyuv me epithelial mucosa hlwb. Rau cov me nyuam mos thiab cov menyuam yaus, yog tias qhov kev ua ntawm lactase hauv cov hnyuv txo qis los yog qhov tso tawm tsis txaus, lactose hauv cov kua mis los yog mis nyuj tsis tuaj yeem ua kom tiav thiab nqus tau, thiab cov tsos mob ntawm lactose intolerance yuav tshwm sim. Cov hmoov dawb, tasteless, tsw, dissolves rau hauv lub teeb xim av kua. Lactose muaj tsawg solubility thiab nyhav rau precipitate tawm nyob rau hauv txias tsiaj cov khoom, muab cov khoom ib tug granular qauv.

Cov txiaj ntsig yog dab tsi?

Lactase rhuav tshem cov lactose ntau dhau hauv lub cev rau hauv qabzib thiab galactose. Glucose yog lub zog rau cov metabolism hauv ntau qhov chaw ntawm tib neeg lub cev, thiab galactose yog cov qauv suab thaj tsim nyog rau cov metabolism hauv tib neeg lub hlwb thiab cov ntaub so ntswg mucous. Nws yog ib qho tsim nyog cov ntaub so ntswg rau me nyuam mos lub hlwb kev loj hlob thiab yog ze ze rau kev loj hlob sai ntawm lub hlwb me nyuam mos. Nws tseem tuaj yeem tsim cov oligosaccharides hauv tib neeg lub cev los ntawm transglycosides, uas yog qhov hnyav molecular, tsis khov, dej-soluble noj fibers. Raws li qhov tshwm sim loj hlob hauv txoj hnyuv, nws tsuas yog siv los ntawm bifidobacteria # tab sis tsis yog los ntawm cov kab mob spoilage. Qhov no tuaj yeem txo qis kev tsim cov co toxins hauv cov hnyuv thiab ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cem quav thiab raws plab.

Lactase-phlorizinhydrolase (LPH) yog ib qho uas tiag tiag hydrolyzes lactose. LPH yog glycoprotein nyob rau hauv microchorion ntawm plab hnyuv epithelial hlwb, nrog qhov zoo tshaj pH ntawm 5.5 mus rau 6. -glucohydrolase).

Catalytic tawg ntawm lactose
Hauv kev lag luam, nws yog siv hauv kev lag luam khoom noj siv mis, siv nws cov hydrolysis los decompose lactose hauv cov khoom noj siv mis los tsim cov khoom noj mis nyuj uas tsis muaj lactose lossis lactose-dawb, uas tuaj yeem noj los ntawm cov neeg uas tsis muaj lactose intolerant. Tsis tas li ntawd, cov kua qaub lactase tuaj yeem ua rau kev kho mob lactase npaj, lossis ntxiv rau cov kua mis hmoov los ua cov kua mis tshwj xeeb, uas yog siv los kho cov tsos mob lactose intolerance, tshwj xeeb tshaj yog rau cov menyuam mos uas nws lub ntsiab ntawm cov khoom noj yog cov khoom noj siv mis. Kev npaj lactase yog qhov zoo tagnrho rau cov menyuam mos thiab menyuam yaus uas tsis muaj lactose intolerant.

Kev hloov ntawm galactosides
Galactose hloov mus rau hauv galacto-oligosaccharides nyob rau hauv qhov kev txiav txim ntawm transglycosides. Cov tshuab no tuaj yeem siv los tsim cov galacto-oligosaccharides. Tam sim no, galacto-oligosaccharides tau muab tso rau hauv khw. Galactooligosaccharides tsis tuaj yeem nqus los ntawm tib neeg lub cev, tab sis tuaj yeem siv los ntawm probiotics xws li bifidobacteria hauv plab hnyuv los txhawb kev loj hlob ntawm probiotics. Lawv yog cov zoo prebiotics, tseem hu ua bifidus yam. Galactooligosaccharides tsuas yog mis niam qhov chaw ntawm prebiotics.

Daim ntawv thov kev taw qhia

1 Feem ntau yog siv rau hauv cov khoom noj mis nyuj, siv nws cov hydrolysis los decompose lactose hauv cov khoom noj siv mis los tsim cov khoom noj mis nyuj uas tsis muaj lactose lossis lactose-dawb rau cov neeg uas muaj lactose intolerant.
2 Galactose hloov mus rau hauv galacto-oligosaccharides nyob rau hauv kev ua ntawm transglycosides. Cov tshuab no tuaj yeem siv los tsim cov galacto-oligosaccharides. Tam sim no, galacto-oligosaccharides tau muab tso rau hauv khw.
3. Feem ntau yog siv rau hauv kev lag luam khoom noj siv mis, nws tuaj yeem hloov tsis muaj qab zib thiab tsis muaj kuab lom lactose rau hauv qab zib, ntau soluble monosaccharides; txo qhov muaj peev xwm ntawm crystallization ntawm lactose hauv dej khov, cov mis nyuj khov, thiab cov mis nyuj evaporated, thaum ua kom qab zib.

Lactase

Synthetic txoj kev hauv vivo

Ua los ntawm preprolactase los ntawm ntau cov kauj ruam:

Prolactase yog tsim los ntawm plaub qhov chaw, uas yog lub teeb liab peptide domain ntawm amino davhlau ya nyob twg, lub extracellular domain, lub hydrophobic transmembrane anchoring cheeb tsam, thiab lub intracellular ntu ntawm carboxyl davhlau ya nyob twg. Raws li kev taw qhia ntawm lub teeb liab peptide, nws nkag mus rau Golgi tom qab kev hloov kho hauv cov endoplasmic reticulum Hauv vivo, nws yog O-glycosylated thiab tom qab ntawd nkag mus rau 2 intracellular thiab luminal cleavages los tsim cov lactase mature.
