NAD+ 1g

Nicotinamide adenine dinucleotide (NAD⁺) is a critical coenzyme found in all living cells. It plays a central role in various biological processes, particularly in energy metabolism and cellular function.

Functions

1. Energy Metabolism:

   • NAD⁺ acts as an electron carrier in cellular respiration.
   • It alternates between its oxidized form (NAD⁺) and reduced form (NADH) during metabolic reactions.
   • NAD⁺ accepts electrons during glycolysis, the citric acid cycle, and oxidative phosphorylation, driving ATP production.

2. DNA Repair:

   • NAD⁺ is a substrate for enzymes like PARPs (poly ADP-ribose polymerases) that repair DNA damage.

3. Gene Expression Regulation:

   • It regulates gene expression by serving as a substrate for sirtuins, a class of proteins involved in aging, stress response, and metabolic regulation.

4. Signal Transduction:

   • NAD⁺ is involved in calcium signaling and other cellular signaling pathways.

5. Cellular Aging:

   • NAD⁺ levels decline with age, contributing to reduced mitochondrial function and increased oxidative stress.

NAD⁺ is indispensable for life, influencing both cellular health and systemic processes. Its role in aging and disease makes it a focus of intense scientific research.
