This energetic dance generates ATP (adenosine triphosphate), our cells' power currency. So, you can thank NAD+ for the pep in your step!
Furthermore, NAD+ is involved in the process of oxidative phosphorylation, which occurs in the mitochondria. This process allows the production of ATP through the transfer of electrons from NADH (the reduced form of NAD+) to the electron transport chain. Without NAD+, our cells would lack the necessary energy to perform their functions efficiently.
NAD+ and DNA Repair
When our DNA gets damaged, NAD+ swoops in to save the day. It activates enzymes called PARPs (poly ADP-ribose polymerases), which detect and repair DNA damage. These enzymes add ADP-ribose units to target proteins, facilitating the recruitment of DNA repair factors and ensuring the integrity of our genetic material. It's like having a team of repairmen constantly inspecting and fixing any tears in our genetic blueprint. Thanks, NAD+ - you've got our back!
Moreover, NAD+ plays a critical role in maintaining the balance between DNA repair and cell death. In situations where DNA damage is irreparable, NAD+ can promote programmed cell death, preventing the propagation of damaged DNA and potential mutations.
