Nicotinamide CAS 98-92-0
Nicotinamide, oo sidoo kale loo yaqaan nicotinamide, fitamiin B3 ama fiitamiin PP, waa fiitamiin biyo-milmi leh oo ka tirsan fiitamiinada B. Waa qayb ka mid ah coenzyme I (nicotinamide adenine dinucleotide, NAD) iyo coenzyme II (nicotinamide adenine dinucleotide phosphate, NADP). Qaybta nicotinamide ee labadan qaab-dhismeedka coenzyme ee jidhka bini'aadamka waxay leedahay hydrogenation-ka iyo sifooyinka fuuq-baxa, waxay door ka ciyaaraan wareejinta hydrogen ee oksaydhka noolaha, waxayna kor u qaadi kartaa neefsiga unugyada, habka oksaydhka noolaha iyo dheef-shiid kiimikaadka.

1. Goobta daryeelka maqaarka
(1) Baro caddeeya oo libdha
Farsamaynta: Waxay joojisaa wareejinta melanin ee melanocytes una gudubta epidermis (walaxda udub dhexaadka u ah dhalada yar ee cad ee OLAY).
Xoog-saarista: 2-5% (Ka sarreeya 5% waxay keeni kartaa xanaaq).
(2) Dayactirka caqabadaha
Dhumucda stratum corneum: Yaraynta khasaaraha biyaha transdermal, ku haboon maqaarka xasaasiga ah (sida looshanka Cerave).
Xididdada dhiigga ee ka-hortagga cas: Yaree guduudashada maqaarka (daryeelka caawiya rosacea).
(3) Anti-gabowga
Kobcinta maqaarka NAD+ : Dib u dhig gabowga gacanta (marka lagu daro horudhaca NAD+ sida NMN).
Iska yaree laalaabkii: Kicin wax-soo-saarka kolajka (Kiliinikada waxaa lagu caddeeyey inay wax ku ool tahay 3% xoogga saarista).
2. Codsiyada beeraha
(1) Nidaaminta koritaanka dhirta:
Kor u qaad iska caabinta walaaca ee dalagyada (sida caabbinta abaarta iyo iska caabinta cadaadiska milixda).
(2) Kor u qaada sunta cayayaanka:
Hagaajinta heerka nuugista foliar ee fungicides qaarkood.
