What does NAD+ do? The main functions of NAD+ are reflected in Mitochondria of somatic cells. Mitochondria are the "power stations of the cell," providing energy to the cell by making the energy-storing molecule Adenosine triphosphate (ATP). In cells, the mitochondria make ATP in a number of different ways. Electron transport chains are one of the most efficient ways to make ATP within mitochondria, which can meet most of the energy needs of the body's cells. In this process, the coenzyme NAD+ acts as a transport mechanism, transporting electrons to the enzymes in the mitochondria and making ATP. When NAD+ accepts electrons, a positively charged hydrogen ion is added to the NAD+ structure to become NADH. NADH then transfers electrons to other enzymes and releases hydrogen ions, turning NADH back into NAD+. After transferring electrons, NAD+ has completed its task. Electrons power enzymes in the mitochondria, which line up neatly to transport electrons from one enzyme to the next until they reach the final step, ATP Synthase, which makes ATP. Finally, ATP is sent throughout the cell, providing energy. In summary, NAD+ is an important electron transport carrier that initiates the electron transport chain that drives mitochondria to manufacture and provide energy.

NAD+, polyADP-ribose polymerase (PARP) and Sirtuins NAD+ interact with other enzymes in addition to ATP Synthase. For example, sirtuins, which regulate cells, and PARPs, which repair DNA, both need NAD+ to help them function. Overeating, drinking, lack of sleep, lack of exercise, and viral infections can cause NAD+ levels to drop in the body, so the mitochondria can overproduce energy and harm cells. Sirtuins and PARPs are playing an important role in cell repair. Unlike ATP Synthase, the role of NAD+ in Sirtuins is not to transfer electrons, but to use NAD+ as a coenzyme in the deacetylation process. PARP uses NAD+ to assist in the ribosylation process. These two processes, assisted by NAD+, are the first steps in an important program for dealing with cellular stress and DNA repair.

Why is NAD+ important?

NAD+ is an important coenzyme that helps our bodies produce energy and carry out many other cellular processes. As simple as drawing air into the lungs or pumping blood into the heart, the chemistry involved depends on NAD+. However, NAD+ 's role in energy production has taken some time to gain public attention. NAD+ was first discovered in 1906 by scientists Arthur Harden and William John Young while studying the fermentation process. Later, Arthur Harden continued Louis Pasteur's earlier work on yeast and tried to gain a better understanding of its metabolic processes. Unfortunately, this research has not received much public attention. Although these findings are a major discovery for the scientific community, the importance of NAD+ has yet to be truly discovered.

By the 1930s, pellagra (also known as "black tongue") was raging in the southern United States, which accelerated research. Pellagra is a deadly disease that causes skin irritation, diarrhea, cognitive impairment and mouth sores, among other symptoms. At that time, Joseph Goldberger discovered that pellagra was caused by vitamin B3 deficiency. His experiments showed that eating milk and yeast relieved the symptoms. Finally, Joseph Goldberger's work led to the formulation of Niacin, the earliest form of vitamin B3. Niacin became an effective nutrient in the treatment of pellagra, and patients showed significant improvement in their condition after taking niacin for a few days. The success of this discovery has led scientists to renew their research on NAD+. Fortunately, pellagra is no longer a common disease. However, research on aging suggests that the health of mitochondria is of Paramount importance in discussions of NAD+. Hassina Massudi, from the Department of Pharmacology at the University of New South Wales, and her team uncovered how the metabolism of NAD changes with age. Studies have shown that human NAD+ levels drop by more than 50% after the age of 40, and the decline in NAD+ levels is closely related to the efficiency of mitochondria. In this wave of NAD+ boom, NAD+ related studies have first found a more effective way to increase the level of NAD+ - Nicotinamide riboside. Until now, we know more about the science behind NAD+ and its role and function in our bodies. Further research is expected to continue to provide encouraging news that challenges the natural phenomenon of human cell aging.
