Folic acid yog cov dej-soluble vitamin nrog cov mis molecular C19H19N7O6, yog li lub npe vim hais tias nws muaj ntau heev nyob rau hauv ntsuab nplooj, kuj hu ua pteroylglutamic acid.Nws muaj nyob rau hauv ntau hom nyob rau hauv cov xwm thiab nws niam nws txiv compound yog ib tug ua ke ntawm 3 yam: pteridine, p-aminobenzoic acid thiab glutamic acid.
Folic acid muaj ib lossis ntau pawg glutamyl, thiab feem ntau tshwm sim ntawm folic acid yog polyglutamic acid cov ntaub ntawv.Cov tshuaj lom neeg ua haujlwm ntawm folic acid yog tetrahydrofolate.Folic acid yog daj crystalline thiab me ntsis soluble hauv dej, tab sis nws cov ntsev sodium yog soluble hauv dej.Nws yog insoluble hauv ethanol.Nws yog yooj yim puas nyob rau hauv acidic daws thiab yog tsis ruaj tsis khov rau tshav kub, yog yooj yim poob nyob rau hauv chav tsev kub, thiab yog heev perishable nyob rau hauv raug rau lub teeb.
Folic acid yog absorbed nyob rau hauv lub cev ob qho tib si nquag thiab passively los ntawm diffusion, feem ntau nyob rau hauv lub Upper ib feem ntawm cov hnyuv.Qhov nqus ntawm folic acid txo qis dua, qhov ntau dua glutamyl qhov nqus tau qis dua, thiab qhov nqus tau yooj yim los ntawm qabzib thiab vitamin C. Tom qab nqus tau, folic acid khaws cia rau hauv cov hnyuv, daim siab, pob txha thiab lwm yam ntaub so ntswg, thiab txo qis rau physiologically active tetrahydrofolate (THFA los yog FH4) enzyme NADPH, uas yog koom nyob rau hauv lub synthesis ntawm purines thiab pyrimidines.Folic acid yog li ua lub luag haujlwm tseem ceeb hauv kev tsim cov protein thiab faib cov cell thiab kev loj hlob, thiab txhawb kev tsim cov qe ntshav liab.Kev tsis txaus ntawm folic acid tuaj yeem ua rau txo qis hauv hemoglobin ntau lawm hauv cov qe ntshav liab thiab ua rau lub cev tsis muaj zog, ua rau megaloblastic anemia.
