Vithamine B3 - e phetha karolo ea bohlokoa ho matla

Metabolism
Vithamine B3, eo hape e tsejoang e le niacin, ke vithamine e qhibilihang metsing e bapalang karolo ea bohlokoa lits'ebetsong tse fapaneng tsa metabolism 'meleng. Lintlha tsa bohlokoa ka vithamine B3 ke tsena:
Mefuta ea vithamine B3:
Niacin e teng ka mefuta e 'meli e meholo: nicotinic acid le nicotinamide. Mefuta ena ka bobeli ke li-precursor tsa li-coenzymes tse bapalang karolo ea bohlokoa ho metabolism ea matla.
Mesebetsi:
Niacin ke selelekela sa li-coenzyme tse peli: nicotinamide adenine dinucleotide (NAD) le nicotinamide adenine dinucleotide phosphate (NADP). Li-coenzyme tsena li nka karolo karabelong ea redox, li bapala karolo ea bohlokoa tlhahisong ea matla, tokiso ea DNA, le mekhoa e fapaneng ea metabolic.
Mehloli ea Niacin:
Mehloli ea lijo ea niacin e kenyelletsa:
Nama (haholo-holo likhoho, tlhapi le nama e mafura)
Linate le peo
Lihlahisoa tsa lebese
Legumes (joaloka matokomane le lentile)
Lithollo tse felletseng
Meroho
Lijo-thollo tse matlafalitsoeng
Niacin Equivalents:
Likahare tsa niacin tsa lijo li ka hlahisoa ka li-niacin tse lekanang le tsona (NE). NE e le 'ngoe e lekana le 1 mg ea niacin kapa 60 mg ea tryptophan, e leng amino acid e ka fetoloang niacin 'meleng.
Khaello:
Khaello e matla ea niacin e ka lebisa ho boemo bo tsejoang e le pellagra, bo khetholloang ke matšoao a kang dermatitis, letšollo, 'dementia', 'me, haeba e sa phekoloe, lefu. Pellagra ha e fumanehe linaheng tse tsoetseng pele empa e ka hlaha ho baahi ba nang le phepo e mpe ea niacin.
Recommended Dietary Allowance (RDA):
Mokhoa o khothaletsoang oa letsatsi le letsatsi oa niacin o fapana ho ea ka lilemo, bong, le boemo ba bophelo. RDA e hlahisoa ka limiligrama tse lekanang le niacin (NE).
Niacin le Bophelo bo Botle ba Pelo:
Niacin e 'nile ea ithutoa bakeng sa melemo ea eona e ka bang teng bophelong bo botle ba pelo. E ka thusa ho eketsa maemo a k'holeseterole e phahameng-density lipoprotein (HDL kapa "ntle") le ho fokotsa boemo ba k'holeseterole e tlaase-density lipoprotein (LDL kapa "bad"). Leha ho le joalo, tlatsetso ea niacin bakeng sa merero ea pelo le methapo e lokela ho etsoa tlas'a tlhokomelo ea bongaka ka lebaka la litla-morao tse ka bang teng.
Niacin Flush:
Tekanyo e phahameng ea niacin e ka baka litlamorao tse tsejoang e le "niacin flush," e khetholloang ka bofubelu, mofuthu le ho hlohlona ha letlalo. Ena ke karabelo ea nakoana ho litlamorao tsa vasodilating ea niacin mme ha e kotsi.
Tlatsetso:
Niacin supplementation hangata ha e hlokahale ho batho ba nang le phepo e nepahetseng. Leha ho le joalo, maemong a mang a bongaka kapa tlas'a tlhokomelo ea bongaka, li-supplement tsa niacin li ka 'na tsa buelloa.
Tšebelisano le Meriana:
Niacin e ka sebelisana le meriana e itseng, ho akarelletsa meriana ea khatello ea mali, meriana ea lefu la tsoekere le li-statins. Batho ba noang meriana ba lokela ho buisana le bafani ba tlhokomelo ea bophelo pele ba noa li-supplement tsa niacin.
Ho netefatsa ho noa ka ho lekaneng ha niacin ka ho ja lijo tse leka-lekaneng ho bohlokoa bakeng sa bophelo bo botle ka kakaretso le ts'ebetso e nepahetseng ea metabolism. Maemong ao ho nahanoang ka tlatsetso, e lokela ho etsoa tlas'a tataiso ea litsebi tsa tlhokomelo ea bophelo.
