NAD+ Peptide

NAD+ is an acronym for Nicotinamide Adenine Dinucleotide, an endogenous nucleotide that is considered to regulate primary functions such as metabolism, energy production, and DNA repair. It is also considered to act as a secondary messenger via calcium-dependent signaling mechanisms, possibly serving as an immunoregulatory component.⁽¹⁾⁽²⁾ NAD+ is considered by researchers to be naturally synthesized via the de novo mechanism of converting the amino acid tryptophan through several enzymatic steps. Researchers posit that there are five components to NAD+ synthesis, including tryptophan, nicotinamide, nicotinic acid, nicotinamide riboside, and nicotinamide mononucleotide.⁽³⁾ Once synthesized, research suggests it exerts over 500 enzymatic reactions and cellular processes⁽¹²⁾ to aid metabolic activities. Essentially, it is suggested to act as a coenzyme in redox functions, converted to NADH (the energy-carrying form of NAD+), which may involve other metabolic pathways.

Overview

Researchers have suggested Nicotinamide Adenine Dinucleotide (NAD+) to act as a coenzyme, with three major classes of enzymes including:

• Deacetylase enzymes in the sirtuin class (SIRTs)
• Poly ADP ribose polymerase (PARPs) enzymes, and
• Cyclic ADP ribose synthetase (cADPRS)

Research suggests that each class of enzymes interacts with NAD+ in the following possible respects:

• SIRTs may stimulate mitochondrial homeostasis, stem cell regeneration, loss of stem cells, and nerve degeneration.
• PARPs, composed of 17 different enzymes, may act alongside NAD+ enzymes and synthesize poly ADP ribose polymers, which may lead to genome stability.
• cADPRS include CD38 and CD157, which are considered to be key immunological cells. cADPRS appears to hydrolyze NAD+ and thereby may stimulate stem cell regeneration and DNA repair, which may be important for maintaining cell cycles.

Researchers suggest the above-mentioned enzymes to be NAD+ dependent enzymes, possibly acting based on the presence of Nicotinamide Adenine Dinucleotide (NAD). Researchers suggest that should all three enzymes be dependent on NAD+, they may potentially compete amongst themselves for bioavailability. It has been posited that the potential function of SIRTs, for instance, may lead to reduced PARPs activity and, thereby, potentially lead to weakened systems. Hence, it may be critical to maintain a balance between the availability and consumption of NAD+ to obtain optimal potential impact.⁽⁵⁾

Research and Clinical Studies

NAD+ Peptide and Productive Aging

Researchers suggest that NAD+ has two key intermediates: nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN). Studies have indicated that these intermediates may be potent agents for promoting 'productive aging.' In a study,⁽⁷⁾ normal-aging mice were exposed to the NMN intermediate for 12 months. Following the study, the researchers suggested that NMN may promote NAD+ synthesis in the mice. Peptide exposure may have been the catalyst for the observed reduced weight gain, increased energy metabolism, enhanced physical activity, improved lipid profile, and other physiological impacts in the mice.
