Nicotinamide Riboside waxaa loo isticmaali karaa daraasadda bayooloji ee hiddo-wadaha dib-u-habaynta dib-u-habaynta ee beerka ee lagu aqoonsaday waddooyinka dheef-shiid kiimikaadka ee gabowga ee jiirka.Waxay sidoo kale kordhisaa NAD + kortex maskaxda waxayna yaraynaysaa xumaanshaha garashada ee qaabka jiirka transgenic ee cudurka Alzheimers.
Nicotinamide adenine dinucleotide (NAD +) waa koenzyme muhiim ah oo, marka lagu dhimo NADH, waxay u adeegtaa sidii wakiil yareynaya si loogu deeqo electrons loogu talagalay fosforyaalka oksaydhka iyo isku dhafka ATP ee mitochondria.NAD+ waa qayb muhiim u ah enzymes sida sirtuins, ADP-ribosyltransferases (ARTs), iyo Poly [ADP-ribose] polymerases (PARPs) waxaana si joogto ah u cuna enzymes-yadan.Saamiga NAD+/NADH waa qayb muhiim ah oo ka mid ah xaaladda dib-u-habaynta unugga.(Verdin 2015).Tirooyinka qaarkood, NAD ama NADP ee la xidhiidha waxay ka qaybqaataan rubuc dhammaan falcelinta unugyada (Opitz Heiland 2015).Waxaa jira qaybo gaar ah oo NAD + ah oo ku jira xudunta, mitochondria, iyo cytoplasm (Verdin 2015).
Nicotinamide riboside (NR) waxaa loo rogi karaa NAD + iyada oo loo marayo tallaabo dhexdhexaad ah taas oo loo beddelo nicotinamide mononucleotide (NMN) by NR kinase (Nrk) ka dibna NAD + by NMNATs.NR waxaa si dabiici ah looga helaa cuntooyinka qaarkood laakiin waa tiro aad u yar (tusaale mikromolar yar).Taariikh ahaan, NR way adkeyd in lagu helo xaddi badan oo la safeeyey, laakiin waxaa mahad leh horumarka hababka isku dhafka ah (Yang 2007), laga bilaabo Juun 2013, waxaa loo iibiyaa kabitaan cunto ah.
