Nikotinamide CAS 98-92-0
Nicotinamide, oo sidoo kale loo yaqaan nicotinamide, fitamiin B3 ama fitamiin PP, waa fiitamiin biyo ku milma oo ka tirsan fiitamiinnada B. Waa qayb ka mid ah coenzyme I (nicotinamide adenine dinucleotide, NAD) iyo coenzyme II (nicotinamide adenine dinucleotide phosphate, NADP). Qaybta nicotinamide ee labada qaab-dhismeedka coenzyme ee jirka bini'aadamka waxay leedahay sifooyin hydrogenation iyo dehydrogenation oo la rogi karo, waxay door ka ciyaartaa wareejinta hydrogen ee oksaydhka bayoolojiga, waxayna kor u qaadi kartaa neefsashada unugyada, habka oksaydhka bayoolojiga iyo dheef-shiid kiimikaadka.

1. Goobta daryeelka maqaarka
(1) Baraha cadaynta iyo libdhashada
Habka: Waxay joojisaa wareejinta melanin ee ka timaadda melanocytes una gudubta epidermis (qaybta ugu muhiimsan ee dhalada cad ee yar ee OLAY).
Xoog-saarid: 2-5% (Ka sarreeya 5% Waxay sababi kartaa cuncun).
(2) Dayactirka xayndaabka
Adkaynta corneum-ka stratum: Yaraynta luminta biyaha maqaarka, oo ku habboon maqaarka xasaasiga ah (sida kareemka Cerave).
Xididdada dhiigga ee ka hortagga casaanka: Yaree casaanka maqaarka (daryeelka kaabista ah ee rosacea).
(3) Ka-hortagga gabowga
Kobcinta maqaarka NAD+: Dib u dhig gabowga unugyada (marka la isticmaalo iyadoo lala kaashanayo waxyaabaha horusocodka ah ee NAD+ sida NMN).
Yaree laalaabyada: Kici wax soo saarka kolajka (Si caafimaad ahaan loo xaqiijiyay waxtarkiisa oo ah 3% fiirsashada).
2. Codsiyada Beeraha
(1) Xeerarka koritaanka dhirta:
Kordhi iska caabbinta walbahaarka ee dalagyada (sida iska caabbinta abaarta iyo iska caabbinta walbahaarka milixda).
(2) Kobciyeyaasha sunta cayayaanka:
Hagaaji heerka nuugista caleenta ee fungicides-ka qaarkood.
