Nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP) are two important coenzymes found in cells. NADH is the reduced form and NAD+ is the oxidized form of NAD.
MH2 + NAD+ → NADH + H+ + M: + energy, where M is a metabolite.
Two hydrogen ions (a hydride ion and an H+ ion) are transferred from the metabolite. Two electrons are transferred to the positively charged nitrogen, and one hydrogen attaches to the carbon atom opposite to the nitrogen.
The human body synthesises NAD from the vitaminniacin in the form of nicotinic acid or nicotinamide.
NADH is directly involved in the body's cellular immune defensive system and the more NADH in your body the better the DNA repair system functions.
NADH, biologically known as Coenzyme 1 (as it is the most important co-enzyme, also known as Co-E1), is the reduced form of nicotinamide adenine dinucleotide (NAD) with high energy hydrogen (H) which provides energy to the cell.
NADH is necessary for thousands of biochemical reactions within the body and is found naturally in every living cell.
