I-Niacinamide noma i-nicotinamide (NAM) uhlobo lwe-vitamin B3 olutholakala ekudleni futhi lusetshenziswa njengesengezo sokudla kanye nemithi. Njengesengezo, isetshenziswa ngomlomo ukuvimbela nokwelapha i-pellagra (ukuntuleka kwe-niacin). Nakuba i-nicotinic acid (niacin) ingasetshenziswa ngale njongo, i-niacinamide inenzuzo yokungabangeli ukukhukhumala kwesikhumba. Njengokhilimu, isetshenziselwa ukwelapha induna. Iyi-vithamini encibilikayo emanzini.
Imiphumela emibi mincane kakhulu. Uma uthatha imithamo ephezulu, izinkinga zesibindi zingase zibe khona. Amanani ajwayelekile aphephile ukusetshenziswa ngesikhathi sokukhulelwa. I-Niacinamide isemndenini wemithi kavithamini B, ikakhulukazi i-vitamin B3 complex. Iyi-amide ye-nicotinic acid. Ukudla okuqukethe i-niacinamide kufaka phakathi imvubelo, inyama, ubisi, nemifino eluhlaza.
I-Niacinamide yatholakala phakathi kuka-1935 no-1937. Isohlwini lweMithi Ebalulekile yeNhlangano Yezempilo Yomhlaba. I-Niacinamide iyatholakala njengomuthi ojwayelekile futhi ngaphandle kwemithi ethengwayo. Kwezentengiselwano, i-niacinamide yenziwe nge-nicotinic acid (niacin) noma i-nicotinonitrile. Emazweni amaningana okusanhlamvu kunezelwe i-niacinamide kukho.
I-NicotinamideIsicelo:
Kungokwe-Vitamin B, ehlanganyela ekusetshenzisweni kwe-metabolism emzimbeni, ingasetshenziswa ukuvimbela i-pellagra noma esinye isifo sokuntuleka kwe-niacin. Isetshenziselwa ikhemisi, isengezo sokudla. Lo mkhiqizo usebenza kanje:
Okokuqala, i-melanin ijulile esikhumbeni seseli le-melanin, kodwa kulokhu, nayo ingaphakathi, kamuva ama-tentacles adluliselwa kumaseli e-keratin azungezile, i-nicotinamide ingaphazamisa ukudluliselwa kwe-melanin, okwenza i-melanin ihlale ngaphakathi ingaphumi, ngakho ngeke iqhubeke nokukhiqiza amaseli e-melanin melanin, Okwesibili, i-melanin ngeke ibonwe ngamehlo omuntu ebusweni besikhumba, ukuze kufezwe umphumela wokwenza mhlophe.
Okwesibili, i-niacinamide ifakazela ukuthi inomphumela omuhle we-saccharification, ikakhulukazi ngemuva kuka-2015, igama elithi "saccharification" licwaningwe kakhulu, izifo eziningi zomzimba zikhombisile ukuthi nge-saccharification (i-maillard reaction), izinto ezikhiqizwa yi-saccharification zinsundu, zingenza isikhumba sibukeke simnyama, ngakho-ke ukumelana ne-mash nakho kuyasiza ekwenzeni mhlophe.
Esivivinyweni esilawulwayo sabantu abangu-20, ukwakheka kwe-nicotinamide okuphindaphindwayo okunezinga eliphansi (0.2%) nakho kuphumelele ekunciphiseni ukucindezeleka kwamasosha omzimba esikhumbeni okubangelwa imisebe ye-UV ebanzi efana nokukhanya kwelanga. U-0.2% wokuhlushwa uyasebenza, futhi ngokuvamile sisebenzisa imikhiqizo yokunakekelwa kwesikhumba esekelwe ku-nicotinamide ukuhlushwa ngokuvamile kungaphezu kuka-2%, ukuhlushwa okungcono kakhulu okungu-4% ~ 5%. Ngakho-ke faka i-nicotinamide extract ngaphambi kokufaka i-sunscreen.
