Vitamin B9 tseem hu ua folate lossis folic acid. Nws yog dej-soluble vitamin uas ua lub luag haujlwm tseem ceeb hauv ntau yam txheej txheem lom neeg. Nov yog qee qhov tseem ceeb ntawm Vitamin B9:
DNA Synthesis thiab Kho:Folate yog qhov tseem ceeb rau kev sib txuas thiab kho DNA. Nws plays lub luag haujlwm tseem ceeb hauv kev faib cell thiab kev loj hlob. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog thaum lub sij hawm ntawm kev faib cell sai thiab loj hlob, xws li thaum cev xeeb tub thiab me nyuam mos.
Kev tsim cov qe ntshav liab:Folate koom nrog hauv kev tsim cov qe ntshav liab (erythropoiesis). Nws ua haujlwm ua ke nrog vitamin B12 los xyuas kom meej qhov tsim nyog thiab kev loj hlob ntawm cov qe ntshav liab, uas yog qhov tseem ceeb rau kev thauj oxygen hauv lub cev.
Neural Tube Development:Kev noj cov folate txaus yog qhov tseem ceeb thaum cev xeeb tub thaum ntxov txhawm rau tiv thaiv kev tsis haum xeeb ntawm cov hlab ntsha hauv cov menyuam hauv plab. Neural tube defects tuaj yeem cuam tshuam kev loj hlob ntawm lub hlwb thiab qaum qaum. Vim li no, ntau lub teb chaws pom zoo kom noj folic acid ntxiv rau cov poj niam uas muaj hnub nyoog me nyuam.
Amino Acid Metabolism:Folate koom nrog hauv cov metabolism ntawm qee cov amino acids, suav nrog kev hloov pauv ntawm homocysteine rau methionine. Kev nce qib ntawm homocysteine yog cuam tshuam nrog kev pheej hmoo ntawm cov kab mob plawv, thiab kev noj cov folate txaus pab tswj cov qib no.
Qhov chaw:Kev noj zaub mov zoo ntawm folate suav nrog cov nplooj ntsuab ntsuab (xws li spinach thiab broccoli), legumes (xws li lentils thiab chickpeas), txiv ntseej, noob, siab, thiab cereals fortified. Folic acid, cov khoom siv hluavtaws ntawm folate, yog siv rau hauv ntau yam tshuaj thiab cov khoom noj muaj zog.
Pom zoo nyiaj pub dawb txhua hnub (RDA):Kev pom zoo txhua hnub ntawm folate sib txawv raws hnub nyoog, poj niam txiv neej, thiab lub neej theem. Cov poj niam cev xeeb tub, piv txwv li, feem ntau xav tau ntau dua. RDA feem ntau yog qhia hauv micrograms ntawm kev noj zaub mov folate sib npaug (DFE).
Tsis muaj peev xwm:Folate deficiency tuaj yeem ua rau megaloblastic anemia, uas yog cov qe ntshav liab loj dua li qub. Nws kuj tuaj yeem ua rau lwm cov tsos mob xws li qaug zog, qaug zog, thiab chim siab. Hauv cov poj niam cev xeeb tub, folate deficiency yog txuam nrog kev pheej hmoo siab ntawm neural tube defects hauv tus me nyuam hauv plab.
Ntxiv:Cov tshuaj Folic acid feem ntau pom zoo rau cov poj niam npaj cev xeeb tub thiab thaum cev xeeb tub thaum ntxov kom txo qis kev pheej hmoo ntawm cov hlab ntsha neural. Cov tib neeg uas muaj qee yam kev mob nkeeg lossis cov uas noj tshuaj tshwj xeeb kuj yuav xav tau kev pab ntxiv.
Folate vs. folic acid
Cov ntsiab lus folate thiab folic acid feem ntau siv sib hloov, tab sis qhov tseeb yog ntau hom vitamin B9. Peb hom tseem ceeb yog:
Folate tshwm sim hauv cov zaub mov thiab hais txog txhua hom vitamin B9, suav nrog folic acid.
Folic acid yog ib daim ntawv hluavtaws (artificial) ntawm B9 uas muaj nyob rau hauv cov tshuaj thiab cov khoom noj muaj zog. Xyoo 1998, Tebchaws Asmeskas xav kom cov tshuaj folic acid ntxiv rau qee cov nplej (nqaij, qhob cij, nplej zom thiab qee cov cereals) kom ntseeg tau tias kev noj zaub mov txaus rau pej xeem. Koj lub cev yuav tsum tau hloov (hloov) folic acid mus rau lwm hom folate ua ntej nws tuaj yeem siv rau kev noj haus.
Methylfolate (5-MTHF) yog lub ntuj, yooj yim-rau-digest daim ntawv ntawm vitamin B9 ntxiv tshaj folic acid. Koj lub cev tuaj yeem siv hom folate tam sim ntawd.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias folate yog rhiab heev rau cua sov thiab lub teeb, yog li kev ua noj ua haus uas khaws cov khoom noj uas muaj folate tuaj yeem pab tswj lawv cov khoom noj muaj txiaj ntsig. Raws li nrog rau cov khoom noj khoom haus, nws yog ib qho tseem ceeb kom ua tiav qhov sib npaug los ntawm kev noj zaub mov sib txawv thiab sib npaug tshwj tsis yog cov xwm txheej tshwj xeeb lossis theem ntawm lub neej xav tau kev pab ntxiv.
