D-Lactose CAS 63-42-3

1. Taw qhia
D-Lactose yog hom qab zib uas muaj nyob hauv cov mis nyuj thiab cov khoom siv mis nyuj. Nws yog ib qho disaccharide ua los ntawm cov piam thaj thiab galactose molecules. Lactose yuav tsum tau tawg los ntawm ib qho enzyme hu ua lactase kom tib neeg zom nws. Qee tus neeg yuav muaj lactose intolerance, uas txhais tau hais tias lawv tsis tsim lactase txaus los rhuav tshem lactose hauv lub cev, ua rau digestive tsis xis nyob.

2. Lub luag haujlwm tseem ceeb
2.1 Muab lub zog
D-Lactose yog ib qho disaccharide ua los ntawm cov piam thaj thiab galactose molecules. Txawm li cas los xij, lactose yuav tsum tau ua ntej tawg rau hauv nws tus kheej monosaccharides los ntawm enzyme lactase ua ntej nws tuaj yeem siv los ua lub zog los ntawm lub cev.
Thaum lactose tau tawg mus rau hauv qabzib thiab galactose, cov suab thaj no tuaj yeem raug metabolized los ntawm ntau txoj hauv kev biochemical los tsim ATP (adenosine triphosphate), lub zog txiaj ntawm lub cev. Tshwj xeeb, cov piam thaj yog metabolized los ntawm cov txheej txheem hu ua glycolysis, uas cuam tshuam cov piam thaj hauv pyruvate los tsim cov ATP me me.
Galactose kuj tseem tuaj yeem metabolized los ntawm txoj kev zoo sib xws, txawm hais tias nws feem ntau xav tau qee cov kauj ruam hloov dua siab tshiab ua ntej nws tuaj yeem siv los ntawm lub cev. Thaum galactose hloov mus rau hauv qabzib, nws tuaj yeem ua ntxiv metabolized los tsim ATP los ntawm glycolysis.
Zuag qhia tag nrho, lactose tuaj yeem muab lub zog rau lub cev hauv daim ntawv ntawm cov piam thaj thiab galactose, uas tuaj yeem metabolized los tsim ATP. Txawm li cas los xij, cov tib neeg uas tsis muaj lactose intolerant, txhais tau tias lawv tsis tuaj yeem tsim cov qib lactase txaus los rhuav tshem cov lactose, tej zaum yuav muaj kev zom zaub mov tsis zoo thiab tsis muaj peev xwm muab tau lub zog los ntawm cov khoom noj uas muaj lactose xws li mis nyuj thiab cheese.

2.2 Txhawb lub plab noj qab haus huv
D-Lactose yog hom qab zib uas muaj nyob rau hauv cov khoom siv mis nyuj uas tuaj yeem pab txhawb plab hnyuv hauv ntau txoj hauv kev. Txoj hauv kev tseem ceeb ntawm lactose txhawb kev noj qab haus huv ntawm plab yog los ntawm kev ua ib qho prebiotic, uas txhais tau hais tias nws tuaj yeem pub cov kab mob zoo hauv plab.
Ib txoj kev tshawb fawb luam tawm nyob rau hauv Phau Ntawv Xov Xwm ntawm Dairy Science pom tias lactose nce tus naj npawb ntawm cov kab mob bifidobacteria zoo hauv plab ntawm cov neeg laus noj qab haus huv. Txoj kev tshawb nrhiav pom tias kev noj cov lactose rau ob lub lis piam ua rau muaj kev nce ntxiv hauv bifidobacteria, uas tau txuas rau kev txhim kho plab hnyuv thiab kev tiv thaiv kab mob.
Lwm txoj kev tshawb fawb luam tawm nyob rau hauv British Journal of Nutrition pom tias lactose supplementation txhim kho plab barrier muaj nuj nqi hauv nas. Cov kws tshawb fawb pom tias lactose nce qhov kev qhia ntawm cov protein uas pab tsim lub plab barrier, uas tuaj yeem tiv thaiv cov kab mob phem thiab co toxins nkag mus rau hauv cov hlab ntsha.
Lactose kuj tau pom tias txo qhov mob hauv plab. Ib txoj kev tshawb fawb luam tawm nyob rau hauv American Journal of Physiology-Gastrointestinal and Liver Physiology pom tias lactose supplementation txo qhov mob hauv plab ntawm npua. Cov kws tshawb fawb tau xaus lus tias lactose tuaj yeem yog cov khoom noj muaj txiaj ntsig zoo rau kev txhim kho plab hnyuv thiab txo qhov mob.
Hauv cov ntsiab lus, lactose tuaj yeem pab txhawb lub plab noj qab haus huv los ntawm kev ua haujlwm ua prebiotic, txhim kho plab kev ua haujlwm, thiab txo qhov mob. Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias lactose intolerance tuaj yeem txo cov txiaj ntsig ntawm kev noj cov lactose, thiab cov neeg uas muaj lactose intolerance yuav tsum sab laj nrog kws kho mob ua ntej noj cov khoom noj siv mis.

2.3 Txhawb kev nqus calcium
Lactose tau pom tias txhawb kev nqus calcium hauv tib neeg lub cev. Lub luag haujlwm tseem ceeb tom qab lactose lub peev xwm los txhawb kev nqus calcium yog cuam tshuam nrog kev tsim cov lactic acid hauv plab.
Thaum noj lactose, nws tau tawg mus rau hauv nws cov monosaccharides, qabzib, thiab galactose, los ntawm enzyme lactase, uas muaj nyob rau hauv cov hnyuv. Cov monosaccharides no ces absorbed rau hauv cov hlab ntsha, thaum lub undigested lactose molecules nkag mus rau hauv cov hnyuv loj.
Hauv cov hnyuv loj, lactose yog fermented los ntawm cov kab mob, uas tsim cov lactic acid. Lactic acid txo qis pH ntawm plab thiab tsim kom muaj ib puag ncig acidic. Qhov chaw acidic no txhawb nqa calcium solubility thiab nqus hauv plab. Tsis tas li ntawd, lactic acid tau pom tias yuav ua rau cov calcium nce ntxiv los ntawm kev txhawb nqa kev qhia ntawm calcium transporters, xws li TRPV6 thiab calbindin-D9k, hauv plab hnyuv.
Ntau qhov kev tshawb fawb tau tshawb xyuas cov txiaj ntsig ntawm lactose rau kev nqus calcium. Ib txoj kev tshawb fawb ntawm cov poj niam postmenopausal pom tias calcium nqus tau nce 12 feem pua ​​​​thaum lactose ntxiv rau lawv cov zaub mov, piv rau pab pawg tswj kev noj calcium ib leeg. Lwm txoj kev tshawb fawb ntawm cov ntxhais hluas pom tias calcium nqus tau nce 16 feem pua ​​​​thaum lactose ntxiv rau cov zaub mov uas muaj calcium.
Hauv cov ntsiab lus, lactose pab txhawb kev nqus calcium los ntawm kev tsim cov lactic acid, uas tsim cov kua qaub ib puag ncig uas txhawb cov calcium solubility thiab nqus, nrog rau nce calcium transporters cov lus qhia hauv plab hnyuv.

2.4 Txhawb kev loj hlob thiab kev loj hlob
Lactose yog thawj carbohydrate uas muaj nyob rau hauv cov mis nyuj, uas yog ib qho tseem ceeb ntawm kev noj haus rau cov me nyuam mos thiab cov me nyuam yaus. Lactose txhawb kev loj hlob thiab kev loj hlob los ntawm kev muab lub zog rau lub cev, pab kev nqus cov as-ham tseem ceeb, thiab txhawb kev loj hlob ntawm cov kab mob hauv plab.
Lactose tau tawg mus rau hauv qabzib thiab galactose hauv cov hnyuv, uas tuaj yeem siv los ntawm lub cev rau lub zog. Glucose tseem yog lub hauv paus ntawm lub zog rau lub hlwb, uas yog qhov tseem ceeb rau kev paub txog kev loj hlob ntawm cov menyuam yaus.
Lactose kuj pab txhawb kev nqus ntawm cov as-ham tseem ceeb xws li calcium, uas yog qhov tseem ceeb rau kev txhim kho pob txha, thiab vitamin D, uas pab txhawb kev nqus thiab siv calcium.
Thaum kawg, lactose txhawb kev loj hlob ntawm cov kab mob hauv plab uas muaj txiaj ntsig zoo, uas ua lub luag haujlwm tseem ceeb hauv plab noj qab haus huv thiab kev tiv thaiv kab mob. Cov kab mob no tseem tsim cov roj ntsha luv luv uas muab lub zog rau lub cev thiab txhawb kev loj hlob thiab kev loj hlob ntxiv.

3. Cov ntawv thov
D-Lactose yog dav siv nyob rau hauv zus tau tej cov me nyuam cov zaub mov, khoom qab zib, margarine, thiab lwm yam. Nws kuj yuav siv tau raws li ib tug kab lis kev cai puag, xim txheej absorber thiab excipient, thiab lwm yam.
