Folic acid waa fitamiin biyo-milmi leh oo leh caanaha molecular C19H19N7O6, oo loo magacaabay sababtoo ah waxay aad ugu badan tahay caleemaha cagaaran, sidoo kale loo yaqaan pteroylglutamic acid.Waxay u jirtaa noocyo kala duwan oo dabiiciga ah iyo xarunteeda waalidku waa isku-darka 3 qaybood: pteridine, p-aminobenzoic acid iyo glutamic acid.
Folic acid waxa ku jira hal ama in ka badan oo kooxaha glutamyl ah, iyo noocyada ugu badan ee folic acid ee si dabiici ah u dhaca waa foomamka polyglutamic acid.Nooca bayooloji ahaan firfircoon ee folic acid waa tetrahydrofolate.Folic acid waa crystalline jaale ah oo wax yar ku milmay biyaha, laakiin cusbada soodhiyamku aad bay ugu milmi kartaa biyaha.Waa mid aan lagu milmi karin ethanol.Si fudud ayaa loogu baabi'iyaa xalalka aashitada sidoo kale waa mid aan degenayn kulaylka, si sahal ahna waa u lumiya heerkulka qolka, aad bayna u baabi'isaa marka ay iftiinku gaadho.
Folic acid waxa ay si firfircoon uga dhex nuugtaa jidhka si firfircooni ah iyo si aan fiicneyn iyadoo la faafinayo, badi ahaan qaybta sare ee mindhicirka yar.Heerka nuugista folic acid hoos ayuu u dhacaa, inta badan glutamyl ayaa hoos u dhigta heerka nuugista, nuugista waxaa fududeeya gulukooska iyo fitamiin C. nuugista ka dib, folic acid waxay ku kaydsan tahay gidaarka mindhicirka, beerka, dhuuxa lafta iyo unugyo kale. waxaana lagu dhimay tetrahydrofolate jir ahaan firfircoon (THFA ama FH4) by enzyme NADPH, kaas oo ku lug leh isku-darka purines iyo pyrimidines.Sidaa darteed Folic acid waxay door muhiim ah ka ciyaartaa isku dhafka borotiinka iyo kala qaybinta unugyada iyo korriinka, waxayna kor u qaadaa samaynta unugyada dhiigga cas ee caadiga ah.Yaraanta folic acid waxay u horseedi kartaa hoos u dhigista wax soo saarka hemoglobin ee unugyada dhiigga cas iyo daciifnimada korriinka unugyada, taasoo keenta dhiig-yaraan megaloblastic ah.
