NAD Pre-Cursor introduction

NAD+ is an important coenzyme, whose full name is nicotinamide adenine dinucleotide. It exists widely within cells and participates in many important biochemical reactions. NAD+ plays a key role in many biological processes, including energy metabolism, cellular respiration, DNA repair, gene transcription, and aging. It can gain or release electrons from it through a variety of biocatalytic reactions. In this process, reactions that NAD+ can catalyze include redox, carbonyl reduction, acyl transfer, etc. As a coenzyme, NAD+'s main function is to transfer electrons and hydrogen ions in enzyme-catalyzed reactions. During this process, NAD+ is reduced to NADH, thereby providing electrons and hydrogen ions for other required enzyme reactions. NAD+ has also attracted considerable scientific attention in recent years because it is thought to be involved in the aging process. Studies have found that during the aging process, the level of NAD+ in cells decreases, and supplementing NAD+ can promote cellular energy metabolism, DNA repair and delay aging. In addition, NAD+ has also been found to play an important role in repairing DNA damage, apoptosis, activating enzymes and regulating gene expression. Currently, people are conducting in-depth research on NAD+ and its role in physiology and pathology, in order to discover more about the functions and applications of NAD+.
