NAD (β-Nicotinamide Adenine Dinucleotide) sodium is an analog of NAD. NAD sodium can be reduced to β-nicotinamide adenine dinucleotide (NADH) when coupled to an oxidative reaction with an organic substrate. NAD sodium can be converted into β-nicotinamide adenine dinucleotide (NADH) and delivered to the interior of mitochondria to indirectly produce ATP.

Biological Activity

Targets	Endogenous metabolite
ln Vitro	Poly(aniline)–poly(styrenesulfonate) composite-coated glassy carbon electrodes are shown to produce a stable, reproducible amperometric response to NADH in citrate–phosphate buffer at pH 7. These responses have been studied as a function of electrode potential, film thickness and both NADH and NAD+ concentration. The results show that the oxidation of NADH occurs throughout the whole of the film and that NAD+, the reaction product, reversibly inhibits the reaction. Rate constants for the different processes have been obtained by kinetic modelling and compared with those previously determined for poly(aniline)–poly(vinylsulfonate) films. Preliminary comparisons imply that diffusion within ‘pores’ in these poly(aniline) composite matrices is important in determining the magnitude of the amperometric responses [1]. Electropolymerisation of aniline in the presence of poly(styrenesulfonate) produces films which are not only stable and electroactive at neutral pH but that are also electrocatalytic surfaces for NADH oxidation. Analysis of the variation of the currents for NADH oxidation as a function of the film thickness, the concentration of NADH, the concentration of NAD+, and the electrode potential shows that NADH oxidation on the poly(aniline)–poly(styrenesulfonate) composite films follows the same mechanism as the reaction on the poly(aniline)–poly(vinylsulfonate) composite films. However, currents for the oxidation of NADH on the poly(aniline)–poly(styrenesulfonate) films are typically three to ten times less than those for the poly(aniline)–poly(vinylsulfonate) films under comparable conditions. From the detailed kinetic analysis this difference in response appears to be mainly due to the lower diffusion coefficient for NADH within the poly(aniline)–poly(styrenesulfonate) film coupled with a lower partition coefficient for NADH into the film. In our previous paper, we pointed out that treating the film as a uniform medium through which NADH was diffusing was an oversimplification and that NADH diffusion was more likely to occur through aqueous pores within the composite film matrix. This proposal receives considerable support from this kinetic analysis which indicates that the more porous poly(aniline)–poly(vinylsulfonate) film, as assessed from SEM measurements, has larger apparent partition and diffusion coefficients for NADH within the film. The comparison between the results obtained for the two different poly(aniline) films highlights the important effect that the physical structures of the films can have on their electrocatalytic properties.[1]

Additional Infomation	Nicotinamide adenine dinucleotide (NAD+) is a coenzyme for redox reactions, making it central to energy metabolism. NAD+ is also an essential cofactor for non-redox NAD+-dependent enzymes, including sirtuins, CD38 and poly(ADP-ribose) polymerases. NAD+ can directly and indirectly influence many key cellular functions, including metabolic pathways, DNA repair, chromatin remodelling, cellular senescence and immune cell function. These cellular processes and functions are critical for maintaining tissue and metabolic homeostasis and for healthy ageing. Remarkably, ageing is accompanied by a gradual decline in tissue and cellular NAD+ levels in multiple model organisms, including rodents and humans. This decline in NAD+ levels is linked causally to numerous ageing-associated diseases, including cognitive decline, cancer, metabolic disease, sarcopenia and frailty. Many of these ageing-associated diseases can be slowed down and even reversed by restoring NAD+ levels. Therefore, targeting NAD+ metabolism has emerged as a potential therapeutic approach to ameliorate ageing-related disease, and extend the human healthspan and lifespan. However, much remains to be learnt about how NAD+ influences human health and ageing biology. This includes a deeper understanding of the molecular mechanisms that regulate NAD+ levels, how to effectively restore NAD+ levels during ageing, whether doing so is safe and whether NAD+ repletion will have beneficial effects in ageing humans. https://pubmed.ncbi.nlm.nih.gov/33353981/
