1. * * Cov Khoom Yooj Yim **
-Airal (FE) yog tshuaj lom neeg nrog cov atomic tus naj npawb ntawm 26, muaj cov hlau sib txuas. Nyob rau hauv qhov, nws mas muaj nyob rau hauv daim ntawv ntawm cov tebchaw, xws li hlau oxide (Fe O3) thiab ferrous sulfide (FES). Hlau muaj ntau tus nqi xeev, feem ntau nrog {{3} ion valence (ferrous ion, fe ion ion, re ion valence (hlau ion, fe ⁺). Nyob rau hauv tib neeg lub cev, hlau tsuas yog txo siab lub cev muaj zog nyob rau hauv daim ntawv ntawm ferous ions.
-From lub tswv yim ntawm lub cev, hlau ntshiab yog ib qho nyiaj dawb hlau nrog kev txhim kho zoo thiab thermal conductivity. Nws tuaj yeem nyiam los ntawm cov hlau nplaum thiab kuj tseem tuaj yeem ua kom muaj kuab.
2. Kev faib tawm thiab cov ntsiab lus hauv tib neeg lub cev **
-Yog yog qhov tseem ceeb tshaj rau tib neeg lub cev, thiab tag nrho cov roj hlau hauv tus neeg laus lub cev yog hais txog {1} grams. Kwv yees li 70% ntawm cov hlau tam sim no hauv kev hemoglobin, uas yog protein nyob hauv cov ntshav liab rau kev thauj cov oxygen. Tsis tas li ntawd, kwv yees li ntawm 3% ntawm cov hlau tam sim no, cov khw muag khoom thiab thauj cov leeg nqaij, pab cov leeg pa roj oxygen thaum qoj ib ce. Ib feem ntawm cov hlau khaws cia rau hauv cov nqaij xws li daim siab ferritin thiab hemosiderin, thiab cov pob txha rov qab ua tau thaum tsim nyog los ntawm lub cev.
3. Kev nqus thiab cov metabolism **
- * * Kev nqus cov av * *: yog tsuas yog nqus nyob rau hauv duodenum thiab suv Jejunum. Hlau hauv cov khoom noj tau muab faib ua heme hlau thiab tsis yog heme hlau. HEME Hlau Nuj Nqis yog los ntawm cov tsiaj cov zaub mov xws li nqaij, ntses, thiab nqaij qaib. Nws cov bioavailability yog siab thiab nws tuaj yeem kho ncaj qha los ntawm cov ntshav plab hnyuv mucosal. Tsis yog heme hlau feem ntau yog los ntawm cov zaub cog ntoo xws li taum pauv, thiab lwm yam. Nws tseem muaj kev cuam tshuam los ntawm ntau yam, xws li mob plab, vitamin C, thiab lwm yam hlau ions.
-Facte uas txhawb nqa cov nqus: Vitamin C tuaj yeem txo qis cov hlau los sis (fe ions (Fe ⁺), yog li txhawb nqa hlau kev nqus. Piv txwv li, thaum kev noj mov hlau nplua nuj, siv cov txiv hmab txiv ntoo (xws li cov txiv kab ntxwv thiab cov zaub txiv hmab txiv ntoo (xws li cov kab mob ntsuab (xws li cov kab mob ntsuab (xws li cov tshuaj ntsuab (xws li nqus tau cov hlau. Ntxiv rau, lub plab acid kuj yuav pab tshem hlau, ua rau nws yooj yim rau nqus.
-Fact cov inhibit nqus: Qee yam tshuaj yuav cuam tshuam cov nqus hlau. Piv txwv li, phytic acid muaj nyob hauv cov nplej, taum, thiab nws tuaj yeem sib xyaw nrog cov hlau ua los ua insoluble complex, txo cov kev nqus hlau. Tannic acid yog tsuas yog tam sim no nyob rau hauv dej tshuaj yej thiab kas fes, thiab kuj tseem muaj kev tsis zoo ntawm kev nqus hlau. Yog li ntawd, nws raug nquahu tias cov neeg hlau tsis muaj kev haus dej ntau thiab haus kas fes thaum noj mov.
-Metabolic txheej txheem: Tom qab kev nqus, ferous ions (Fe ⁺) Nkag mus rau cov roj plab hnyuv (Fe) Lwm qhov yuav nkag mus rau cov ntshav, khi nrog ntau cov nqaij mos thiab thiab cov kabmob, Myoglobin, lossis lwm yam hlau muaj cov enzymes.
4. * * Lub Cev Muaj Zog **
-Oxygen Thauj: Raws li tau hais ua ntej, hlau yog qhov tseem ceeb tivthaiv ntawm hemoglobin. Cov hlau ions hauv hemoglobin tuaj yeem kho tau txoj hlua khi nrog cov pa oxygen. Thaum cov ntshav ntws los ntawm lub ntsws, hemoglobin khi nrog oxygen los ua oxygenated hemoglobin; Thaum cov ntshav ntws los ntawm cov ntaub so ntswg, oxygenated Hem Based oxygen rau cov ntaub so ntswg los ua pa. Tus txheej txheem no yog qhov tseem ceeb rau kev tswj cov kev ua haujlwm ib txwm ua haujlwm thiab lub zog metabolism hauv tib neeg lub cev. Yog tias cov tshuaj hlau tshwm sim, nws tuaj yeem ua rau txo qis hauv hemoglobin synthesis, txo qis hauv oxygen thauj ntshav muaj peev xwm.
- * * Koom nrog hauv lub zog metabolism * *: Hlau yog ib feem ntawm ntau cov enzymes koom nrog kev ua pa cellular, xws li Cytochrome thiab succinate dehydrogenase. Cov enzymes no ua si lub luag haujlwm tseem ceeb hauv oxidative phosphorylation, txhawb kev tsim cov zog ntawm intracellular lub zog (ATP). Yog li ntawd, hlau yog qhov tseem ceeb rau kev tswj kom muaj zog metabolism thiab kev ua haujlwm ntawm cov hlwb.
-Cov muaj nuj nqi: Hlau ua haujlwm: Hlau kuj ua lub luag haujlwm hauv lub cev tiv thaiv kab mob. Nws koom nrog kev muaj peev xwm thiab sib txawv ntawm cov lymphocytes, thiab cov hlau sib tw pab kom muaj kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv hniav ib txwm muaj. Txawm li cas los xij, hlau overload tej zaum kuj tseem muaj cov teebmeem tsis zoo rau kev tiv thaiv kab mob, raws li qee cov kab tuaj yeem siv cov hlau tshaj plaws rau kev loj hlob dhau los thiab luam.
5. Tsis muaj thiab ntau tshaj **
-Air Qhov: Hlau Phom Tsis Txaus yog ib qho ntawm cov khoom noj muaj txiaj ntsig zoo tshaj plaws thoob ntiaj teb. Nyob rau hauv thaum ntxov theem ntawm cov khoom tsis txaus, lub cev yuav siv cov hlau ntim khaws cia kom muaj cov tsos mob tshwm sim. Raws li cov kav hlau tsis muaj zog, ua pa tsis txaus, ua pa ntawm kev ua tsis taus pa, tsis muaj zog, tsis muaj kev tiv thaiv, thiab tsis muaj zog. Hlau tsis txaus hauv cov menyuam yaus kuj yuav cuam tshuam rau lawv txoj kev loj hlob, kev loj hlob, thiab kev muaj peev xwm thiab kev txawj ntse.
-Txhua hlau kom tsis txhob ua rau cov hlau lom. Kev siv hlau lom feem ntau yog tshwm sim los ntawm kev noj cov hlau ntau, ntuav, mob plab, thiab mob plab zom mov. Thaum muaj mob hnyav, tej zaum nws yuav yog kev phom sij. Mobile Hlau Tshaj yog mas pom nyob rau qee cov kab mob uas yog muaj keeb meem (xws li cov kabmob ntshav, uas muaj peev xwm ua rau mob siab, xws li tus mob khaub thuas, mob ntshav qab zib, ntshav qab zib, thiab lwm yam.
6. * * Cov ntaub ntawv noj zaub mov thiab cov lus pom zoo noj zaub mov **
-Qhov chaw: Qhov zoo tshaj plaws ntawm cov hlau yog tsiaj lub siab, cov nqaij ntshav, thiab nqaij liab (xws li nqaij nyuj thiab nqaij npuas. Legumes, zaub nplooj ntsuab (xws li txaws, txiv ntoo, thiab lwm cov nroj tsuag cov khoom noj kuj muaj cov hlau, tab sis tsis yog tus neeg muaj kev sib haum xeeb.
- * * Cov Lus Qhia Ntxiv * *: Rau cov neeg tsis muaj kev coj noj coj ua, kho lawv cov qauv kev noj haus yuav tuaj yeem nce lawv cov hlau hlau. Yog tias kev hloov kho cov khoom noj muaj txiaj ntsig tseem tsis tuaj yeem ua tau raws li cov kev xav tau, cov tshuaj txhuam hniav tuaj yeem raug coj raws li tus kws kho mob lossis zaub mov noj. Cov tshuaj pab hlau tuaj nyob rau hauv ntau hom ntawv, xws li ferrous sulfate, ferrous fumarate, thiab lwm yam pom zoo kom lawv tom qab noj mov kom txo cov plab zom mov. Nyob rau tib lub sijhawm, txhawm rau txhim kho cov tshuaj haum ntawm hlau, nws tuaj yeem ua ke nrog cov vitamin C.
