NAD+-dependent enzymatic reactions:

Sirtuin activation : NAD+ serves as a substrate for sirtuins (class III histone deacetylases), including SIRT1, SIRT3, and SIRT6. These enzymes regulate gene expression, mitochondrial function, and DNA repair processes, contributing to cellular stress resistance and aging modulation.

Redox homeostasis maintenance: The NAD+/NADH ratio acts as a key redox sensor, regulating metabolic flux and antioxidant responses. This balance modulates pathways involved in reactive oxygen species (ROS) detoxification, preventing oxidative damage to cellular components.

The multifunctional roles of NAD⁺ integrate metabolic regulation, stress responses, and longevity pathways, making it a pivotal target in research on age-related diseases, metabolic disorders, and cellular homeostasis. Its depletion during aging and pathological conditions underscores its significance in maintaining physiological function.
