Cov nyhuv ntawm mannose ntawm cov ntshav qab zib tsawg heev, thiab nws tuaj yeem hais tau tias "yuav luag tsis muaj txiaj ntsig" rau cov ntshav qab zib. Qhov no yog qhov sib txawv tseem ceeb ntawm nws thiab feem ntau lwm cov suab thaj xws li qabzib.

Nov yog cov lus piav qhia ntxaws:

Cov txheej txheem metabolic sib txawv:

Glucose: Nws yog lub hauv paus ntawm lub zog rau lub cev. Nws tau txais txiaj ntsig zoo los ntawm txoj hnyuv (yuav luag 100%), nkag mus rau hauv cov hlab ntsha (nce ntshav qab zib), thiab raug coj mus, siv, lossis khaws cia los ntawm cov hlwb nrog kev pab ntawm insulin (xws li glycogen, rog).

Mannose: Txawm hais tias nws kuj yog ib qho monosaccharide (rau carbon qab zib), nws txoj kev metabolic hauv lub cev yog qhov txawv ntawm cov piam thaj.

Tsawg nqus tau: Cov hnyuv nqus tau zoo ntawm mannose qis dua li cov piam thaj (kwv yees li 20% lossis qis dua).

Tsis nyob ntawm cov tshuaj insulin: Tom qab nkag mus rau hauv daim siab, feem ntau ntawm cov mannose yog phosphorylated rau hauv mannose-6-phosphate los ntawm cov enzymes tshwj xeeb (tsuas yog mannose kinases).

Kev hloov pauv mus rau Fructose-6-phosphate: Mannose-6-phosphate yog tom qab hloov mus rau Fructose-6-phosphate los ntawm phosphomannose isomerase.

Nkag mus rau txoj hauv kev glycolysis: Fructose-6-phosphate yog ib qho khoom nruab nrab hauv glycolysis txoj hauv kev uas tuaj yeem ua rau metabolized ntxiv los tsim lub zog. Qhov tseem ceeb yog qhov kev hloov pauv no hla cov kauj ruam tseem ceeb xws li glucokinase thiab qabzib-6-phosphate, thiab tsis nyob ntawm qhov kev ua ntawm insulin. cov

Tsis txhob stimulating insulin secretion:

?

Vim lub fact tias mannose nws tus kheej tsis yog lub ntsiab stimulant ntawm tsub kom cov ntshav qab zib (nrog ib tug me me nkag mus rau hauv cov hlab ntsha thiab txawv metabolic txoj kev), nws tsis ho txhawb pancreatic beta hlwb kom secrete insulin zoo li qabzib. Kev tshawb fawb tau pom tias kev tswj hwm qhov ncauj ntawm mannose tsis ua rau cov ntshav qabzib nce siab thiab qib insulin.

Cov pov thawj kho mob thiab kev sim:

?

Qee qhov kev tshawb fawb me me ua rau cov neeg noj qab haus huv thiab cov neeg mob ntshav qab zib hom 2 tau pom tias txawm tias muaj cov koob tshuaj ntau heev (xws li 0.2 g / kg lub cev hnyav, uas yog sib npaug rau 14 g rau 70 kg tus neeg), qhov ncauj mannose tsis ua rau muaj kev hloov pauv hauv cov ntshav qabzib ntau.

Cov kev sim tsiaj kuj tseem qhia tau hais tias mannose tsis nce ntshav qab zib.

Soj ntsuam cov laj thawj vim li cas mannose muaj kev cuam tshuam me me rau cov ntshav qab zib:

?

Tsawg nqus tau: Feem ntau ntawm cov mannose noj tsis tau nqus thiab siv ncaj qha los yog tawm los ntawm cov kab mob hauv plab.

Txoj hauv kev tshwj xeeb hauv metabolic: Cov khoom nqus tau sai sai hloov mus rau hauv fructose-6-phosphate hauv lub siab los ntawm txoj kev ywj pheej ntawm insulin thiab nkag mus rau glycolysis, tsis txhob khiav ncaj qha raws li cov ntshav qabzib (glucose).

Tsis muaj cov tshuaj insulin tsis txaus: Tsis muaj kev txhawb nqa cov ntshav qab zib kom zoo, yog li nws tsis ua rau muaj cov tshuaj insulin tseem ceeb.

Daim ntawv ceeb toom tseem ceeb:

Cov koob tshuaj: Cov lus xaus saum toj no feem ntau yog raws li cov lus pom zoo ntxiv (feem ntau yog siv rau kev noj qab haus huv ntawm cov zis, nyob ib ncig ntawm 1-2 grams tauj ib hnub) thiab qee qhov kev tshawb fawb (xws li 0.2g / kg). Hauv txoj kev xav, koob tshuaj ntau heev tuaj yeem tsim cov teeb meem metabolic sib txawv, tab sis lawv feem ntau tsis siv rau lub hom phiaj no.

Qab Zib: Qhov qab zib ntawm mannose yog kwv yees li 70% ntawm sucrose, tab sis qee zaum nws tau hais tias muaj peev xwm "qis glycemic Performance index sweetener" vim tias nws tsis cuam tshuam rau cov ntshav qab zib thiab nqus tau tsawg dua. Tab sis nws cov nqi thiab saj (me ntsis iab) raws li cov khoom qab zib txwv nws cov ntawv thov dav.

Kev siv tseem ceeb: Tam sim no, daim ntawv thov tseem ceeb ntawm mannose yog raws li nws lub peev xwm los cuam tshuam cov kab mob sib txuas (tsuas yog Escherichia coli) rau cov kab mob urinary epithelial, rau kev tiv thaiv thiab kho cov kab mob urinary tract (UTIs). Nws cov txiaj ntsig zoo ntawm cov piam thaj hauv cov ntshav ua rau nws muaj kev nyab xeeb rau cov neeg mob ntshav qab zib lossis cov neeg uas muaj ntshav qab zib mellitus thaum lawv xav tau los tiv thaiv cov kab mob urinary (qhov tseeb, lawv tseem yuav tsum ua raws li tus kws kho mob cov lus qhia).

Kev sib txawv ntawm tus kheej thiab kev sab laj nrog kws kho mob: Txawm hais tias cov txheej txheem metabolic txiav txim siab tias nws tsis cuam tshuam rau cov ntshav qab zib, tej zaum yuav muaj qhov sib txawv ntawm tib neeg. Yog tias koj muaj mob ntshav qab zib mellitus lossis lwm yam kab mob metabolic, nws yog qhov zoo dua mus ntsib kws kho mob ua ntej siv mannose ntxiv.

Xaus:

Mannose yog cov suab thaj tshwj xeeb uas, vim nws txoj hnyuv tsis txaus thiab qhov tshwj xeeb, insulin ywj siab metabolic txoj hauv siab, tsis tshua ua rau cov ntshav qab zib nce ntxiv thiab tsis txhawb nqa cov tshuaj insulin. Qhov no ua rau nws muaj kev nyab xeeb ntau dua rau cov neeg uas xav tswj cov ntshav qab zib (xws li cov neeg mob ntshav qab zib) dua li lwm cov suab thaj, tshwj xeeb tshaj yog thaum siv los tiv thaiv kab mob urinary.
