Biological Pathways

  • Cellular redox biology — NAD+ cycles between oxidised and reduced forms as a carrier of electrons in metabolism.
  • Mitochondrial metabolism — it is central to energy-producing pathways within the mitochondria.
  • Sirtuins and PARP enzymes — NAD+ acts as a substrate for these enzyme families, which are studied in DNA repair and cellular maintenance.

Mechanism Of Interest

NAD+ is studied as a coenzyme central to cellular redox biology, cycling between oxidised (NAD+) and reduced (NADH) forms.

Research examines its role in mitochondrial metabolism and the cellular processes that rely on redox coenzyme activity.

Sirtuins are a family of enzymes that use NAD+ as a substrate and are studied in the context of cellular maintenance and ageing research.

PARP enzymes also consume NAD+ and are studied within DNA-repair biology.

Why Researchers Are Interested

  • It is a foundational coenzyme referenced throughout cellular biology literature.
  • It provides a model for studying redox biology and cellular energy pathways.
