NADmolekylen

NADmolekylen, or Nicotinamide Adenine Dinucleotide, is a vital coenzyme found in all living cells. It plays a critical role in a multitude of metabolic processes, most notably in energy production. NAD exists in two forms: NAD+ (oxidized) and NADH (reduced). The ratio of these two forms is crucial for cellular health and function.

In its oxidized form, NAD+ acts as an electron acceptor, facilitating the transfer of electrons in cellular respiration. This process, occurring primarily in the mitochondria, generates adenosine triphosphate (ATP), the main energy currency of the cell. NAD+ is also a substrate for enzymes like PARPs (poly(ADP-ribose) polymerases) and sirtuins, which are involved in DNA repair, gene expression, and cellular stress responses.

As a product of metabolic reactions, NAD+ can be converted into NADH by accepting electrons. NADH then carries these electrons to the electron transport chain, another key component of ATP synthesis. The interconversion between NAD+ and NADH is a dynamic cycle that is essential for maintaining cellular energy balance.

The levels of NAD+ naturally decline with age, a phenomenon that has been linked to various age-related diseases and functional decline. Consequently, research into methods for boosting NAD+ levels, such as through dietary supplements or specific interventions, is an active area of scientific inquiry. Understanding the multifaceted roles of NADmolekylen is fundamental to comprehending cellular metabolism and aging processes.
