Folate vs Folic Acid
Tshuaj, ob qho tib si folic acid thiab folate tej zaum yuav suab ntau dua los yog tsawg tib yam li folate yog cov ionized daim ntawv ntawm cov kua qaub tom qab poob ib tug proton ua nws carboxylate anion. Txawm li cas los xij, qhov sib txawv ntawm folic acid thiab folate yog ntau ntawm kev lom neeg. Ntawm no ob qho tib si no raug xa mus rau cov khoom noj khoom haus thiab ntau dua kev noj haus ntxiv raws li lawv yog cov ntaub ntawv ntawm cov dej soluble vitamin B. Nws yog ib qho tseem ceeb kom tswj tau qhov tseeb ntawm cov vitamin B hauv lub cev vim nws yog ib qho tseem ceeb ntawm cov vitamin rau ntau lub cev ua haujlwm. Tab sis tib neeg tsis tuaj yeem tsim cov folate hauv lub cev thiab, yog li ntawd, yuav tsum tau noj los ntawm kev noj haus, kom ua tau raws li qhov yuav tsum tau ua txhua hnub. Cov lus folic acid thiab folate yog muab los ntawm Latin lo lus 'folium' uas txhais tau tias 'nplooj'.
Folic acid tsis tshwm sim hauv cov zaub mov. Lwm cov tshuaj siv feem ntau yog siv thaum qhov xav tau ntawm folate hauv lub cev tsis tau txais los ntawm cov khoom noj. Folic acid yog ib hom zoo li no, tab sis nws yog ib hom hluavtaws, thiab txoj kev folic acid yog metabolized yog qhov txawv ntawm txoj kev folate metabolized hauv kev noj haus hauv lub cev.
txhawm rau nkag mus rau lub voj voog loj folate metabolic, folate lossis lwm yam kev siv ntxiv (piv txwv li folic acid) yuav tsum tau hloov mus rau 'tetrahydrofolate' (THF). Yog li kom tau txais cov khoom no, folic acid tau txais kev txo qis hauv thawj zaug (ntxiv cov electrons / H atoms) ua raws li cov kauj ruam methylation (txuas ib pawg 'methyl') hauv daim siab, thiab tom qab ntawd hloov mus rau THF yuav tsum muaj cov enzyme ntxiv hu ua 'dihydrofolate. reductase'. Kev ua haujlwm zoo ntawm cov enzyme no yog qhov tseem ceeb txhawm rau txhawm rau txhawm rau folic acid kom zoo thiab tsim cov THF qhov xav tau kom ua tau raws li lub cev cov vitamin B.
Ntawm qhov tod tes, kev ua haujlwm tsawg dua ntawm cov enzyme, lossis kev noj ntau dua ntawm folic acid ntau tshaj qhov txwv ua rau cov folic acid unmetabolized mus rau hauv cov ntshav thiab tuaj yeem ua rau mob qog noj ntshav. Tsis tas li ntawd, vim muaj cov tshuaj folic acid uas tsis tau ua tiav, qhov xav tau folate yuav tsum tau npog thiab ib tus tuaj yeem xaus kev txom nyem los ntawm vitamin B tsis txaus. Tias yog vim li cas nws yog qhov zoo tshaj plaws kom tau txais folate ib txwm los ntawm cov khoom noj es tsis txhob tso siab rau cov tshuaj ntxiv.
Yog li ntawd, folic acid nws tus kheej tsis ua haujlwm lom; Nws dhau los ua ib qho tseem ceeb tsuas yog tom qab kev hloov pauv ntawm tetrahydrofolate thiab lwm yam derivatives rau hauv dihydrofolic acid hauv daim siab.
Folate
Folate yog cov ntsiab lus dav dav siv rau ib pawg ntawm cov dej soluble B vitamins thiab hais txog ntau yam THF derivatives ib txwm muaj nyob hauv cov zaub mov. Qhov zoo tshaj plaws thiab txoj kev noj qab haus huv tshaj plaws los ua kom tiav ib qho kev xav tau folate yog los ntawm cov khoom noj ntuj raws li lwm hom kev noj zaub mov folate tau ua ke nrog ntau yam kev pheej hmoo rau kev noj qab haus huv thaum noj ntau dhau. Tab sis kev noj txaus ntawm folate nplua nuj zaub mov yog qhov tseem ceeb rau kev noj qab haus huv. Tib neeg lub cev xav tau folate los ua ke thiab kho DNA, los pab kev faib cov cell sai thiab loj hlob tshwj xeeb tshaj yog thaum cev xeeb tub thiab cev xeeb tub. Folate tseem xav tau rau kev tsim cov qe ntshav liab noj qab haus huv txhawm rau tiv thaiv cov kab mob anemic. Tsis zoo li folic acid, folate ib txwm metabolizes rau hauv THF hauv txoj hnyuv me thiab nkag mus rau lub voj voog metabolic sai dua nrog tsawg dua enzyme dependencies dua folic acid.
Cov khoom noj muaj folate muaj xws li zaub nplooj (spinach, broccoli, lettuce), txiv hmab txiv ntoo (bananas, lemons), cereals, okra, asparagus, kua txiv lws suav, nceb thiab lwm yam.
Qhov txawv ntawm Folic Acid thiab Folate yog dab tsi?
• Folate yog ib daim ntawv ntawm cov vitamin B ib txwm tshwm sim hauv cov zaub mov thaum folic acid yog cov khoom siv ntawm cov vitamin no.
• Cov metabolism ntawm folic acid hauv tib neeg lub cev yuav tsum tau ua ntawm ib qho enzyme ntxiv hu ua 'dihydrofolate reductase' hauv daim siab, qhov folate nkag mus rau hauv lub voj voog metabolism sai.
• kev noj folic acid ntau dua (los ntawm cov tshuaj ntxiv) tuaj yeem ua rau mob qog noj ntshav, tab sis tsis muaj kev phom sij rau kev noj qab haus huv cuam tshuam nrog kev noj cov folate los ntawm cov zaub mov ntuj.
