Solution thermodynamics of aqueous nicotinic acid solutions in presence of tetrabutylammonium hydrogen sulphate [PDF]

Journal of the Serbian Chemical Society, 2013
In this study we investigated the effects of tetrabutylammonium hydrogen sulphate (Bu4NHSO4) on the solute-solute and solute-solvent interactions in the aqueous solutions of nicotinic acid in terms of apparent molar volumes (φV), standard partial ...

Nrt1 and Tna1-independent export of NAD+ precursor vitamins promotes NAD+ homeostasis and allows engineering of vitamin production. [PDF]

PLoS ONE, 2011
NAD(+) is both a co-enzyme for hydride transfer enzymes and a substrate of sirtuins and other NAD(+) consuming enzymes. NAD(+) biosynthesis is required for two different regimens that extend lifespan in yeast.

Scientific Opinion on the safety and efficacy of niacin (nicotinic acid and nicotinamide) as a feed additive for all animal species based on a dossier submitted by Lonza Benelux BV [PDF]

EFSA Journal, 2012
<p>The term ‘niacin’ is used as a generic description of nicotinic acid and nicotinamide with pyridine as the basic structure. Nicotinic acid and nicotinamide function mainly as precursors of the co-enzymes NAD and NADP.

Lack of nicotinic acid effect on cholesterol metabolism of the rat*

Journal of Lipid Research, 1960
The effect of the addition of 1 per cent nicotinic acid to the diet of the rat on serum, liver, and carcass cholesterol, and on the incorporation of acetate-1-C14 into cholesterol by the intact animal were studied.
