What Is The Difference Between NAD, NAD+, And NADH?

NAD, NAD+, and NADH: A Quick Breakdown

NAD (Nicotinamide Adenine Dinucleotide):
- The base molecule.
- Exists in two primary forms: NAD+ and NADH.
NAD+ (Oxidized Form):
- Acts as an electron acceptor.
- Involved in cellular respiration, where it helps convert energy from food into ATP.
- Lower NAD+ levels are associated with aging and various diseases.
NADH (Reduced Form):
- Acts as an electron donor.
- Carries electrons from metabolic processes to the electron transport chain, where they are used to generate ATP.
- Higher NADH levels indicate increased cellular energy production.
