Nhanganyaya
Niacinamide, inozivikanwawo senicotinamide, vhitamini B3 kana vhitamini PP, ivhitamini inonyungudika mumvura uye iri mumavhitamini B. Chikamu che niacinamide chiri mumaumbirwo maviri aya e coenzyme mumuviri wemunhu chine hunhu hwekuwedzera Chemicalbook hydrogen uye dehydrogenation, iyo inoita basa mukuoxidation yemuviri. Kutapurirana kwehydrogen kunogona kukurudzira kufema kwenyama, maitiro ekuoxidation yemuviri uye metabolism, izvo zvakakosha zvikuru pakuchengetedza hutano hwenyama dzakajairwa, kunyanya ganda, nzira yekugaya uye sisitimu yetsinga. Kana isina kukwana, inokonzera prosthema nekuti kufema uye metabolism yemasero zvinokanganiswa.
Hunhu hwemakemikari
Niacinamide ipfu chena yakaita sekristaro kana kristalo, haina hwema kana kuti inonhuwa zvishoma, uye inovava zvishoma. Huremu hwayo i1.4, uye poindi yekunyunguduka i129-131℃. 1g yechigadzirwa ichi inonyungudika mu1mL yemvura, 1.5mL yeethanol kana 10mL yeglycerine, uye hainyungudike muether. Yakasimba zvishoma. Inodzivirira acid, alkali uye tembiricha yepamusoro. Yakasimba kuchiedza nekupisa mumhepo yakaoma. Kana ichipiswa mualkaline kana acidic solutions, inogadzira niacin.
Basa remuviri
Kugona kwakanaka kwekudzivirira makwinya Kugona kweniacinamide kurwisa makwinya ndekwekuti inogona kumutsa ChemicalbookATP, kupa simba kumasero ekeratin, kuwedzera kugadzirwa kwecollagen, uye ine hukama hwakanaka, iyo inogona kushandiswa nezvimwe zvinhu zvinodzivirira makwinya. Zvidzidzo zvakawanda zvekumba nekune dzimwe nyika zvakaratidza kuti niacinamide inogona kuderedza zvakanyanya kuitika kwekudzivirira kweganda kubva mukupiswa nemwaranzi ye ultraviolet.
