Nicotinic acid ndi chinthu chofunikira popereka haidrojeni ndikumenyana ndi pellagra mu zamoyo;imathandizira kuti khungu ndi mitsempha ikhalebe ndi thanzi komanso imathandizira chimbudzi.
Nicotinic acid kapena niacinamide amagwiritsidwa ntchito pochiza ndi kupewa pellagra.Awa ndi matenda omwe amayamba chifukwa cha kuchepa kwa niacin.Niacin imagwiritsidwanso ntchito pochiza cholesterol yayikulu.Nthawi zina, niacin yotengedwa ndi colestipol imatha kugwira ntchito limodzi ndi colestipol ndi mankhwala a statin.
Niacin USP granular imagwiritsidwa ntchito pakulimbitsa chakudya, monga zakudya zowonjezera komanso ngati mankhwala apakatikati.
Chakudya cha niacin chimagwiritsidwa ntchito ngati mavitamini a nkhuku, nkhumba, zoweta, nsomba, agalu ndi amphaka, ndi zina zotero. Amagwiritsidwanso ntchito ngati pakati pa nicotinic acid zotumphukira ndi ntchito zaukadaulo.
Niacin amadziwikanso kuti vitamini B3.Ndi mankhwala osungunuka m'madzi omwe amachititsa kuti khungu likhale lolimba, louma, kapena lophwanyika, zomwe zimathandiza kuti khungu likhale losalala komanso labwino.niacin amawonjezera maonekedwe ndi maonekedwe a tsitsi, mwa kuwonjezera thupi, kusungunuka, kapena kuwala, kapena kukonzanso tsitsi lomwe lawonongeka mwakuthupi kapena ndi mankhwala.Akagwiritsidwa ntchito popanga mankhwala osamalira khungu, niacinamide ndi niacin amapangitsa kuti khungu louma kapena lowonongeka liwonekere pochepetsa kuphulika ndi kubwezeretsanso kuyanika.
Nicotinic acid.Ndi kalambulabwalo wa coenzymes NAD ndi NADP.Kugawidwa kwambiri mu chilengedwe;ndalama zoyamikirika zimapezeka m'chiwindi, nsomba, yisiti ndi mbewu za chimanga.Kuperewera kwa zakudya kumalumikizidwa ndi pellagra.Mawu akuti "niacin" adagwiritsidwanso ntchito.
Niacin ndi vitamini b-complex sungunuka m'madzi yomwe imafunikira kuti kukula ndi thanzi la minofu.Zimalepheretsa pellagra.Imakhala ndi kusungunuka kwa 1 g mu 60 ml ya madzi ndipo imasungunuka mosavuta m'madzi otentha.Ndizokhazikika posungira ndipo palibe kutaya komwe kumachitika mu kuphika wamba.Magwero ake ndi chiwindi, nandolo, ndi nsomba.Poyambirira idatchedwa nicotinic acid ndipo imagwiranso ntchito ngati chopatsa thanzi komanso chopatsa thanzi.
Nicotinic acid.Ndi kalambulabwalo wa coenzymes NAD ndi NADP.Kugawidwa kwambiri mu chilengedwe;ndalama zoyamikirika zimapezeka m'chiwindi, nsomba, yisiti ndi mbewu za chimanga.Kuperewera kwa zakudya kumalumikizidwa ndi pellagra.Mawu oti "niacin" amagwiritsidwanso ntchito ponena za nicotinamide kapena zotumphukira zina zomwe zikuwonetsa zochita za nicotinic acid.Vitamini (enzyme cofactor).
Nicotinic acid yapangidwa kuti italikitse zotsatira za itshypolipidemic.Pentaerythritol tetranicotinate yakhala yothandiza kwambiri poyesera kuposa niacin pochepetsa milingo ya kolesterolini mwa akalulu.Ma polyesters a sorbitol ndi myo-inositolhexanicotinate akhala akugwiritsidwa ntchito pochiza odwala omwe ali ndi atherosclerosis obliterans.Mankhwalawa amaperekedwa nthawi yakudya kuti achepetse kukwiya kwapamimba komwe nthawi zambiri kumatsagana ndi Mlingo waukulu.
