I-Nicotinamide, i-Pyridine-3-Carboxyamide | I-C6H6N2O | 122.13 |
Ukunyibilika: Incibilika ngokukhululekile emanzini nasetshwaleni, inyibilika ku-glycerin
I-Niacinamide noma i-nicotinamide (NAM) iwuhlobo lukavithamini B3 olutholakala ekudleni futhi lusetshenziswa njengesengezo sokudla kanye nemithi.Njengesengezo, isetshenziswa ngomlomo ukuvimbela nokwelapha i-pellagra(ukuntula kwe-niacin).Nakuba i-nicotinic acid (niacin) ingase isetshenziselwe le njongo, i-niacinamide inenzuzo yokungabangeli ukuguquguquka kwesikhumba.Njengokhilimu, isetshenziselwa ukwelapha izinduna.Kuyivithamini encibilika emanzini.
Imiphumela engemihle mincane.Ngemithamo emikhulu kungase kuvele izinkinga zesibindi.Amanani avamile aphephile ukusetshenziswa ngesikhathi sokukhulelwa.I-Niacinamide isemndenini kavithamini B wemithi, ikakhulukazi i-vitamin B3 complex.Kuyi-amide ye-nicotinic acid.Ukudla okuqukethe i-niacinamide kuhlanganisa imvubelo, inyama, ubisi, nemifino eluhlaza.
I-Niacinamide yatholwa phakathi kuka-1935 no-1937. Isohlwini Lwemithi Ebalulekile Yenhlangano Yezempilo Yomhlaba.I-Niacinamide itholakala njengomuthi ojwayelekile nangaphandle kwekhawunta.Ngokwezentengiselwano, i-niacinamide yenziwa nge-nicotinic acid (niacin) noma i-nicotinonitrile.Emazweni amaningana okusanhlamvu kunezelwa i-niacinamide kuwo.
Iyingxenye ye-Vitamin B, ebamba iqhaza ku-metabolism emzimbeni, ingasetshenziswa ukuvimbela i-pellagra noma esinye isifo se-niacin defection.Isetshenziselwa ikhemisi, i-additi yokudlaLo mkhiqizo usebenza kanje:
Okokuqala, i-melanin ijulile esikhumbeni se-melanin cell, kodwa kulokhu, futhi ngaphakathi, kamuva amatende adluliselwa kumaseli e-keratin azungezile, i-nicotinamide ingaphazamisa ukudluliselwa kwe-melanin, yenza i-melanin ibe yi-melanocyte ihlale ngaphakathi ukuze ingafiki. out, ngakho ngeke uqhubeke ukukhiqiza melanin melanin amangqamuzana, Okwesibili, melanin ngeke kubonwe iso lomuntu phezu kwesikhumba, ukuze kuzuzwe umphumela mhlophe.
Okwesibili, i-niacinamide ifakazela ukuthi inomphumela omuhle we-saccharification, ikakhulukazi ngemuva kuka-2015, igama elithi "saccharification ucwaningo olunzulu kakhulu, izifo eziningi ze-physiological zabonisa ukuthi nge-saccharification (i-maillard reaction), izinto ezikhiqizwa yi-saccharification zinsundu, zingavumela. isikhumba sibukeka simnyama, ngakho ukumelana ne-mash kusiza futhi ku-whitening.ves, izithasiselo zokudla, izimonyo, njll.
Esivivinyweni esilawulwayo sezifundo ezingu-20, amajazi aphindaphindiwe aphindaphindiwe e-nicotinamide ekugxiliseni okuphansi (0.2%) nawo aphumelele ekwehliseni ukuvinjelwa kokuzivikela komzimba okubangelwa imisebe ye-UV ene-spectrum emincane elingisa ukukhanya kwelanga.I-0.2% ye-concentration iyasebenza, futhi ngokuvamile sisebenzisa imikhiqizo yokunakekelwa kwesikhumba esekwe ku-nicotinamide ngokuvamile ingaphezu kuka-2%, ukugxiliswa okuhle kakhulu kuka-4% ~ 5%.Ngakho sebenzisa i-nicotinamide ekhishwe ngaphambi kokufaka i-sunscren.
