I-Niacinamide okanye i-nicotinamide (NAM) luhlobo lwevithamin B3 efumaneka ekutyeni kwaye isetyenziswa njengesongezelelo sokutya kunye namayeza. Njengesongezelelo, isetyenziswa ngomlomo ukuthintela kunye nokunyanga i-pellagra (ukunqongophala kweniacin). Ngelixa i-nicotinic acid (niacin) inokusetyenziselwa le njongo, i-niacinamide inenzuzo yokungabangeli ukugungxulwa kwesikhumba. Njenge-cream, isetyenziselwa ukunyanga i-acne. Yivithamini enyibilikayo emanzini.
Iziphumo ebezingalindelekanga zincinci. Kwidosi ephezulu iingxaki zesibindi zisenokwenzeka. Izixa eziqhelekileyo zikhuselekile ukuba zisetyenziswe ngexesha lokukhulelwa. I-Niacinamide ikusapho lwe-vitamin B kusapho lwamayeza, ngakumbi i-vitamin B3 complex. Yi-amide ye-nicotinic acid. Ukutya okuneniacinamide kubandakanya igwele, inyama, ubisi, kunye nemifuno eluhlaza.
I-Niacinamide yafunyanwa phakathi kuka-1935 kunye no-1937. Ikuluhlu lwaMayeza ayimfuneko kuMbutho wezeMpilo weHlabathi. I-Niacinamide iyafumaneka njengeyeza elenziwe lafana nalawo aveliswe ngumenzi nakwikhawuntara. Urhwebo, i-niacinamide yenziwe nge-nicotinic acid (niacin) okanye i-nicotinonitrile. Kumazwe amaninzi iinkozo zongezwa iniacinamide kuzo.
INicotinamideIsicelo:
I-Vitamin B, ethatha inxaxheba kwi-metabolism emzimbeni, ingasetyenziselwa ukukhusela i-pellagra okanye esinye isifo se-niacin defection. Isetyenziselwa ikhemesti, i-additi yokutyaLe mveliso isebenza ngolu hlobo lulandelayo:
Okokuqala, i-melanin inzulu eluswini lweseli ye-melanin, kodwa ngeli xesha, nayo ngaphakathi, kamva iintente zikhutshelwa kwiiseli ze-keratin ezijikelezileyo, i-nicotinamide inokuphazamisana nokudluliselwa kwe-melanin, yenza i-melanin ibe yi-melanocyte ihlale ngaphakathi ukuba ingaphumi, ngoko ayiyi kuqhubeka ivelisa iiseli ze-melanin melanin, okwesibini, i-melanin ayiyi kubonwa ngeso lesikhumba somntu, ukuze ibonakale kwiliso lomntu.
Okwesibini, i-niacinamide ingqina ukuba inesiphumo esihle se-saccharification, ngakumbi emva kwe-2015, igama elithi "i-saccharification yophando olunzulu kakhulu, izifo ezininzi ze-physiological zibonise ukuba kunye ne-saccharification (impendulo ye-maillard), izinto eziveliswa yi-saccharification zimdaka, zinokuvumela ulusu lubonakale lumnyama, ngoko ke ukuxhathisa kwe-mash kunceda kwi-whitening.ves, izongezo zokutya, njl njl.
Kulingo olulawulwayo lwezifundo ze-20, iingubo eziphindaphindiweyo ze-nicotinamide kwi-concentration ephantsi (0.2%) nazo ziphumelele ekunciphiseni ukugonywa kwesikhumba okubangelwa yimisebe ye-UV emincinci efana nokukhanya kwelanga. I-0.2% yogxininiso lusebenza kakuhle, kwaye ngokuqhelekileyo sisebenzisa i-nicotinamide esekelwe kwiimveliso zokunakekelwa kwesikhumba ukugxininiswa ngokubanzi kungaphezulu kwe-2%, i-concentration engcono ye-4% ~ 5%. Ke sebenzisa isicatshulwa se-nicotinamide ngaphambi kokufaka i-sunscren.
