Qhov sib txawv tseem ceeb ntawm lub xeev nqus thiab lub xeev postabsorptive yog lub xeev nqus yog lub xeev uas zom cov zaub mov thiab nqus cov as-ham rau hauv peb cov hlab ntsha thaum lub xeev postabsorptive yog lub xeev uas cov khoom nqus tsis tau tshwm sim, thiab lub cev tso siab rau. lub zog reserves rau lub zog.
Cells tsim lub zog los ntawm qabzib, lipids thiab amino acids. Lawv khaws cov khoom tsim muaj zog ua rog, glycogen thiab cov proteins. Thaum lub sij hawm lub zog metabolism, cov tshuaj hloov pauv hloov mus ua kom lub zog siv tau. Muaj peb theem ntawm lub zog metabolism. Peb theem no yog theem cephalic, theem nqus thiab theem yoo mov lossis lub xeev postabsorptive. Yog li ntawd, peb lub cev tau txais kev nqus thiab postabsorptive xeev txhua hnub. Lub xeev nqus tau tshwm sim tam sim ntawd tom qab txhua pluas noj thaum lub sijhawm postabsorptive yuav siv qhov chaw thaum lub GI ib ntus khoob thiab tom qab kev nqus ntawm cov as-ham tag.
Lub Xeev Absorptive yog dab tsi?
Absorptive xeev lossis lub xeev pub yog lub sijhawm tam sim tom qab noj mov. Thaum noj cov zaub mov pib digestion, cov as-ham yog absorbed rau hauv cov ntshav. Feem ntau, lub xeev no khiav rau 4 teev tom qab noj mov. Yog li ntawd, ib hnub twg, peb lub cev siv tag nrho 12 teev nyob rau theem nqus yog tias peb noj peb zaug. Hauv lub xeev no, peb lub cev nyob ntawm lub zog uas tau nqus los ntawm cov zaub mov.
Glucose yog lub zog tseem ceeb hauv lub xeev no. Sib nrug los ntawm cov piam thaj, cov roj me me thiab cov amino acids muab lub zog rau peb lub cev thaum lub xeev no. Ntxiv cov as-ham ntxiv tsis nqus rau hauv peb cov hlab ntsha. Lawv khaws cia hauv cov ntaub so ntswg. Yog li, cov piam thaj ntau dhau hloov mus rau glycogen hauv daim siab thiab cov leeg hlwb. Cov roj ntau dhau yog tso rau hauv cov ntaub so ntswg adipose. Tsis tas li ntawd, cov khoom noj muaj roj ntau dhau tau tso ua triglycerides hauv cov ntaub so ntswg adipose
Daim duab 01: Absorptive State
Nyob hauv lub xeev nqus, insulin yog cov tshuaj hormones tseem ceeb uas pab muab cov piam thaj rau hauv cellular noj thiab khaws cia. Ntxiv nrog rau cov tshuaj insulin, kev loj hlob hormone, androgens thiab estrogens kuj koom nrog kev nqus cov as-ham rau hauv cov ntshav.
Postabsorptive State yog dab tsi?
Postabsorptive xeev lossis lub xeev yoo mov yog lub sijhawm pib tom qab ua tiav ntawm kev nqus cov as-ham. Hauv cov lus yooj yim, lub xeev postabsorptive yog lub xeev uas peb cov kab mob GI tsis muaj zaub mov. Yog li ntawd, thaum muaj kev xav tau ntawm lub zog, peb lub cev tso siab rau lub zog endogenous reserves. Internal zog reserves yuav tsum tau tawg mus ua kom tiav lub zog xav tau nyob rau hauv lub xeev no. Peb lub cev pib cia siab rau glycogen khw muag khoom qab zib. Tom qab ntawd nws nyob ntawm triglycerides. Glucagon yog cov enzyme uas ua haujlwm tseem ceeb hauv lub xeev no. Lwm yam tshaj li glucagon, epinephrine, kev loj hlob hormone thiab glucocorticoids kuj koom nrog hauv lub xeev postabsorptive.
Daim duab 02: Postabsorptive State
Zoo ib yam li lub xeev nqus, lub xeev postabsorptive kuj tseem siv sijhawm 4 teev thaum sawv ntxov, yav tav su thiab yav tsaus ntuj. Yog li ntawd, ib hnub twg, peb siv 12 teev nyob rau hauv lub xeev postabsorptive.
Dab tsi yog qhov zoo sib xws ntawm Absorptive thiab Postabsorptive State?
- Absorptive xeev thiab postabsorptive xeev yog ob lub xeev ua haujlwm metabolic tshwm sim hauv peb lub cev.
- Peb siv sijhawm 12 teev hauv txhua lub xeev ib hnub.
- Lub siab, cov leeg nqaij, thiab cov ntaub so ntswg adipose ua lub luag haujlwm tseem ceeb hauv ob lub xeev.
- Cells xav tau lub zog hauv ob lub xeev rau lawv cov haujlwm ntawm tes.
Qhov txawv ntawm Absorptive thiab Postabsorptive State yog dab tsi?
Absorptive xeev pib tam sim tom qab noj cov zaub mov. Thaum lub sijhawm no, kev zom zaub mov thiab nqus cov as-ham rau hauv cov ntshav tshwm sim. Lub caij no, lub xeev postabsorptive pib tom qab ua tiav kev nqus ntawm cov as-ham. Thaum lub sij hawm lub xeev no, peb lub cev siv zog khaws cia nyob rau hauv endogenous zog reserves. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm kev nqus thiab postabsorptive xeev. Tsis tas li ntawd, insulin ua lub luag haujlwm tseem ceeb hauv lub xeev nqus, thaum glucagon plays lub luag haujlwm tseem ceeb hauv lub xeev postabsorptive.
Cov hauv qab no infographic muab ntau qhov sib piv ntsig txog qhov sib txawv ntawm lub xeev nqus thiab postabsorptive.
Summary – Absorptive vs Postabsorptive State
Absorptive xeev thiab postabsorptive xeev yog ob lub xeev tseem ceeb ntawm lub zog metabolism. Thaum lub sijhawm nqus dej, peb lub cev zom cov zaub mov thiab nqus cov as-ham rau hauv cov ntshav. Yog li, lub xeev no pib tam sim tom qab noj zaub mov. Hauv qhov sib piv, lub xeev postabsorptive pib tom qab kev nqus tag nrho ntawm cov as-ham thiab thaum GI ib puag ncig yog khoob. Nyob rau hauv lub xeev no, peb lub cev tso siab rau lub zog khaws cia nyob rau hauv reserves. Yog li ntawd, kev nqus cov as-ham tsis tshwm sim thaum lub sijhawm no. Thaum xav txog 24 teev sijhawm lossis ib hnub, peb siv ze li 12 teev hauv lub xeev nqus thiab 12 teev hauv lub xeev postabsorptive. Qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm lub xeev absorptive thiab postabsorptive xeev.
