Taw qhia
Phosphate yog ib qho ntxhia tshwm sim uas yog qhov tseem ceeb rau ntau yam txheej txheem lom neeg hauv lub cev. Nws ua lub luag haujlwm tseem ceeb hauv kev tsim cov pob txha thiab cov hniav, lub zog metabolism, thiab DNA synthesis. Phosphate muaj nyob rau hauv ntau yam khoom noj, ob qho tib si ib txwm muaj thiab ua ib qho ntxiv. Hauv tsab xov xwm no, peb yuav tham txog dab tsi phosphate hauv zaub mov yog, nws txoj haujlwm, qhov chaw, thiab muaj feem cuam tshuam txog kev noj qab haus huv.
Kev ua haujlwm ntawm phosphate hauv lub cev
Phosphate yog ib qho tseem ceeb ntawm ntau yam kab mob lom, xws li DNA, RNA, thiab ATP (adenosine triphosphate), uas yog lub hauv paus ntawm lub zog rau cov txheej txheem ntawm tes. Phosphate kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tsim cov pob txha thiab cov hniav, vim nws yog ib feem tseem ceeb ntawm hydroxyapatite, cov ntxhia matrix uas muab cov pob txha thiab cov hniav lawv lub zog thiab kav ntev.
Tsis tas li ntawd, phosphate muaj kev koom tes hauv ntau txoj hauv kev ntawm cov xov tooj ntawm tes, pab tswj kev loj hlob ntawm tes, kev loj hlob, thiab kev sib txawv. Nws kuj ua haujlwm tsis zoo, pab tswj cov pH sib npaug ntawm cov kua hauv lub cev, xws li ntshav thiab zis.
Hom Phosphate hauv Khoom Noj
Phosphate hauv cov zaub mov tuaj yeem muab faib ua ob hom: organic thiab inorganic.
Organic phosphate yog ib txwm muaj nyob rau hauv ntau yam khoom noj uas yog ib feem ntawm ntau yam lom molecules, xws li DNA, RNA, thiab phospholipids. Piv txwv ntawm cov khoom noj uas muaj cov phosphate muaj xws li nqaij, ntses, mis nyuj, txiv ntseej, thiab noob.
Inorganic phosphate, ntawm qhov tod tes, yog ntxiv rau ntau cov zaub mov ua tiav ua ib qho ntxiv. Nws feem ntau yog siv los ua cov tshuaj tiv thaiv, pH regulator, thickener, thiab leavening agent hauv cov khoom ci. Inorganic phosphate additives suav nrog sodium phosphate, potassium phosphate, thiab calcium phosphate, thiab lwm yam.
Qhov chaw ntawm Phosphate hauv Khoom Noj
Phosphate muaj nyob rau hauv ntau yam khoom noj, ob qho tib si ib txwm muaj thiab ua ib qho ntxiv. Qee cov khoom noj uas tshwj xeeb tshaj yog nplua nuj nyob hauv phosphate muaj xws li:
- Nqaij thiab nqaij qaib: Nqaij nyuj, nqaij npuas, nqaij qaib, thiab ntses yog txhua yam zoo ntawm cov organic phosphate.
- Cov khoom noj mis: Mis, cheese, thiab yogurt muaj ob qho tib si organic thiab inorganic phosphate.
- Txiv ntseej thiab noob: Almonds, cashews, sunflower noob, thiab taub dag noob yog tag nrho cov siab nyob rau hauv organic phosphate.
- whole grains: Brown mov, whole wheat bread, thiab oats muaj ob qho tib si organic thiab inorganic phosphate.
- Cov zaub mov ua tiav: Ntau yam khoom noj ua tiav, xws li dej qab zib, deli nqaij, thiab khoom noj txom ncauj, muaj cov khoom siv tsis muaj phosphate.
Muaj peev xwm cuam tshuam txog kev noj qab haus huv ntawm phosphate hauv zaub mov
Txawm hais tias phosphate yog qhov tseem ceeb rau ntau yam txheej txheem lom neeg hauv lub cev, kev noj phosphate ntau dhau tuaj yeem cuam tshuam rau kev noj qab haus huv. Cov qib phosphate hauv cov ntshav siab, ib yam mob hu ua hyperphosphatemia, tuaj yeem ua rau lub raum puas, kab mob plawv, thiab cov pob txha tsis muaj zog.
Kev noj ntau dhau ntawm inorganic phosphate additives, tshwj xeeb, tau txuas rau cov txiaj ntsig kev noj qab haus huv. Cov kev tshawb fawb tau pom tias kev noj ntau ntawm cov tshuaj phosphate tuaj yeem ua rau muaj kev pheej hmoo ntawm cov kab mob plawv, kab mob raum, thiab kev tuag tag nrho.
Tsis tas li ntawd, qee qhov kev tshawb fawb tau qhia tias cov tshuaj inorganic phosphate additives tuaj yeem ua rau muaj kev loj hlob ntawm qee yam mob qog noj ntshav, xws li mob qog noj ntshav. Txawm li cas los xij, xav tau kev tshawb fawb ntxiv kom paub tseeb tias cov kev tshawb pom no.

Phosphate yog ib qho tseem ceeb ntxhia uas ua lub luag haujlwm tseem ceeb hauv ntau yam txheej txheem lom neeg hauv lub cev. Nws muaj nyob rau hauv ntau yam khoom noj, ob qho tib si lawm thiab raws li ib tug additive. Thaum noj cov phosphate nruab nrab feem ntau muaj kev nyab xeeb thiab muaj txiaj ntsig, kev noj ntau dhau ntawm cov tshuaj phosphate tuaj yeem cuam tshuam rau kev noj qab haus huv. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov txog peb cov phosphate kom tsawg thiab xaiv cov khoom noj muaj txiaj ntsig zoo thaum twg los tau.
