What is the Meaning of NAD+ Metabolism?

NAD+ Metabolism encompasses the intricate biochemical pathways responsible for the synthesis, utilization, and recycling of Nicotinamide Adenine Dinucleotide ($text{NAD}^+$) and its related forms within the cell. $text{NAD}^+$ is an essential coenzyme required for hundreds of redox reactions and is a critical substrate for $text{NAD}^+$-consuming enzymes, including sirtuins and $text{PARPs}$. Declining cellular $text{NAD}^+$ levels are a recognized hallmark of aging, making its metabolic regulation a key target for longevity and hormonal optimization strategies. Maintaining high $text{NAD}^+$ levels is vital for cellular energy production.

What is the Origin of NAD+ Metabolism?

The discovery of $text{NAD}^+$ dates back to 1906, with its role in cellular respiration elucidated over the subsequent decades. The concept of "$text{NAD}^+$ metabolism" as a longevity target gained significant attention in the early 21st century with the discovery of sirtuins and the recognition of age-related $text{NAD}^+$ depletion. This established $text{NAD}^+$ as a central node linking energy status, DNA repair, and the overall aging process.

What is the Mechanism of NAD+ Metabolism?

$text{NAD}^+$ is synthesized primarily through the salvage pathway, utilizing precursors like nicotinamide riboside ($text{NR}$) and nicotinamide mononucleotide ($text{NMN}$) to rapidly replenish cellular pools. The coenzyme functions as an electron acceptor in catabolic pathways, such as glycolysis and the Krebs cycle, and as a substrate for signaling enzymes. Its consumption by sirtuins, which regulate gene expression and stress resistance, links $text{NAD}^+$ availability directly to genomic stability and endocrine health.
