Message definition (Nicotinamide riboside)
The identification of Nicotinamide riboside (NR) as an NAD precursor in [[eukaryotes]] developed out of the study of [[pellagra]]. Pellagra was the first disease to be associated with NAD+ deficiency. It was linked to nutritional deficiency by [[Joseph Goldberger]] in 1914, and to deficiency of [[Niacin (substance)|niacin]] ([[Vitamin B3|vitamin B<sub>3</sub>]]) by [[Conrad Elvehjem]] in 1937.  NAD+ (then called coenzyme I)  was shown to be extremely low in cases of pellagra, and NA and NAM were identified as molecular precursors in rebuilding NAD+ levels. Pellagra is now understood as a severe, chronic depletion of NAD+, which can be treated through diet.
