I-Niacinamide okanye i-nicotinamide (NAM) luhlobo lwe-vitamin B3 efumaneka ekutyeni kwaye isetyenziswa njengesongezelelo sokutya kunye namayeza. Njengesongezelelo, isetyenziswa ngomlomo ukuthintela nokunyanga i-pellagra (ukungabikho kwe-niacin). Nangona i-nicotinic acid (niacin) ingasetyenziselwa le njongo, i-niacinamide inenzuzo yokuba ayibangeli ukurhawuzelela kolusu. Njengekhrimu, isetyenziselwa ukunyanga i-acne. Yivithamini enyibilikayo emanzini.
Iziphumo ebezingalindelekanga zincinci. Xa uneedosi eziphezulu, iingxaki zesibindi zinokubakho. Ubungakanani obuqhelekileyo bukhuselekile ukusetyenziswa ngexesha lokukhulelwa. I-Niacinamide ikusapho lwe-vitamin B lwamayeza, ngakumbi i-vitamin B3 complex. Yi-amide ye-nicotinic acid. Ukutya okuqulethe i-niacinamide kuquka igwele, inyama, ubisi, kunye nemifuno eluhlaza.
I-Niacinamide yafunyanwa phakathi kowe-1935 nowe-1937. Ikuluhlu lwamayeza abalulekileyo e-World Health Organisation. I-Niacinamide iyafumaneka njengeyeza eliqhelekileyo kwaye ayithengiswa ngaphandle kwekhawuntara. Kwintengiso, i-niacinamide yenziwe nge-nicotinic acid (niacin) okanye i-nicotinonitrile. Kumazwe aliqela iinkozo zongezwa kwi-niacinamide.
I-NicotinamideIsicelo:
YeyeVitamin B, ethatha inxaxheba kwimetabolism emzimbeni, ingasetyenziselwa ukuthintela i-pellagra okanye esinye isifo sokungasebenzi kakuhle kwe-niacin. Isetyenziselwa ikhemesti, isongezo sokutya. Le mveliso isebenza ngolu hlobo lulandelayo:
Okokuqala, i-melanin inzulu eluswini lweseli ye-melanin, kodwa ngeli xesha, nayo ngaphakathi, kamva ii-tentacles zidluliselwa kwiiseli ze-keratin ezijikelezileyo, i-nicotinamide inokuphazamisana nokudluliselwa kwe-melanin, yenza i-melanin ihlale ngaphakathi ingaphumi, ngoko ayiyi kuqhubeka ivelisa iiseli ze-melanin ze-melanin, Okwesibini, i-melanin ayiyi kubonwa ngamehlo omntu kumphezulu wesikhumba, ukuze kufezekiswe isiphumo sokuba mhlophe.
Okwesibini, i-niacinamide ibonakalise ukuba inefuthe elihle le-saccharification, ingakumbi emva kowama-2015, igama elithi "saccharification" liphandwe kakhulu, izifo ezininzi ze-physiological zibonise ukuba nge-saccharification (i-maillard reaction), izinto eziveliswa yi-saccharification zimdaka, zinokwenza ulusu lubonakale lumnyama, ngoko ke ukumelana ne-mash kukwanceda ekwenzeni mhlophe.
Kwilingo elilawulwayo labantu abangama-20, ii-coats eziphindaphindwayo ze-nicotinamide kwi-concentration ephantsi (0.2%) nazo zisebenze kakuhle ekunciphiseni ukucinezelwa kwamasosha omzimba eluswini okubangelwa yimitha ye-UV enqamlezileyo efana nelanga. I-0.2% yoxinzelelo iyasebenza, kwaye sihlala sisebenzisa iimveliso zokhathalelo lolusu ezisekelwe kwi-nicotinamide uxinano luhlala lungaphezulu kwe-2%, uxinano olungcono lwe-4% ~ 5%. Ngoko ke faka i-nicotinamide extract ngaphambi kokufaka i-sunscreen.
