The Elusive Role of NAD+: Unveiling the Mysteries of Cellular Energy Metabolism
NAD+ (Nicotinamide adenine dinucleotide) is a crucial cofactor in cellular energy metabolism, yet its precise role remains shrouded in mystery. This review aims to provide an overview of the current understanding of NAD+
NAD+ is a vital molecule that plays a central role in maintaining cellular homeostasis. As a cofactor in redox reactions, it facilitates the transfer of electrons in various metabolic pathways, including glycolysis, the citric acid cycle, and fatty acid oxidation. However, despite its importance, the exact mechanisms by which NAD+ regulates these processes remain poorly understood. Recent studies have implicated NAD+ in the regulation of epigenetic marks, DNA repair, and cellular stress responses, further highlighting its multifaceted role in cellular metabolism. The missing role of NAD+ refers to the lack of a comprehensive understanding of its specific functions and how they intersect with other cellular processes. This review aims to provide a comprehensive overview of the current state of knowledge on NAD+ and its involvement in various cellular processes, with the ultimate goal of identifying areas for further research and potential therapeutic targets.
