Tarihin Nicotinamide adenine dinucleotide

Masanin kimiyyar nazarin halittu na Burtaniya Arthur Harden da William John Young ne suka fara gano coenzyme NAD + a cikin shekarar 1906. Sun lura cewa ƙara dafaffun yisti da aka cire ya ba da hanzarta saurin shan giya a cikin abubuwan da aka toya yisti. Sun kira abin da ba a san shi ba wanda ke da alhakin wannan sakamako a matsayin hanyar samar da bayanai. Ta hanyar tsayi mai wahala da tsabtace ruwan daga yisti, wannan fasalin mai kwanciyar hankali an gano shi azaman nucleotide sugar phosphate ta Hans von Euler-Chelpin. A cikin 1936, masanin kimiyyar Bajamushe Otto Heinrich Warburg ya nuna aikin kwayar halittar nucleotide coenzyme a cikin canja wurin hydride kuma ya gano kashi na nicotinamide a matsayin shafin yanar gizo na redox halayen.

An gano farkon maganan Vitamin na NAD + a cikin 1938, lokacin da Conrad Elvehjem ya nuna cewa hanta tana da aikin "harshen baƙar fata" a cikin hanyar nicotinamide. Bayan haka, a cikin 1939, ya ba da babbar hujja ta farko cewa ana amfani da niacin don haɗa NAD + .A farkon shekarun 1940, Arthur Kornberg shine farkon wanda ya gano wani enzyme a cikin hanyar nazarin halittu. A cikin 1949, masanan sunadarai na Amurka Morris Friedkin da Albert L. Lehninger ya tabbatar da cewa NADH ya haɗu da hanyoyin hanyoyin rayuwa kamar su citric acid zagaye tare da kira na ATP a cikin oxidative phosphorylation. A cikin 1958, Jack Preiss da Philip Handler sun gano tsaka-tsakin da enzymes da ke cikin kwayar halittar NAD +; Kiran salvage daga acid nicotinic ana kiransa hanyar Preiss-Handler. A cikin 2004, Charles Brenner da abokan aiki sun gano hanyar nicotinamide riboside kinase zuwa NAD +

1. Yana kunna Enzymes Wanda Zai Iya Inganta Zamani Lafiya

2. Zai iya Taimaka Kare swayoyin kwakwalwa

NAD + yana taka rawa wajen taimakawa sel kwakwalwa.

A cikin ƙwayoyin kwakwalwa, NAD + yana taimakawa sarrafa samarwar PGC-1-alpha, furotin wanda ya bayyana don taimakawa kare ƙwayoyin cuta daga stressarfin oxyidative da nakasa aikin mitochondrial. Masu binciken sun yi imanin cewa damuwar rashin karfin jiki da nakasa aikin mitochondrial suna da nasaba da cututtukan kwakwalwa da suka shafi shekaru kamar cutar Alzheimer da ta Parkinson.
