NADH (nicotinamide adenine dinucleotide)

NADH (nicotinamide adenine dinucleotide) is a key molecule in cellular energy production. It acts as a carrier of electrons, helping cells convert nutrients like glucose into usable energy. During metabolic processes, NADH picks up electrons and stores energy, which are later transferred to generate ATP, the main energy currency of the cell. Essentially, NADH is vital for powering many biological functions and maintaining overall cell health, functioning as an essential part of the body's energy metabolism.
