NDAPH （nicotinamide adenine dinucleotide phosphate) includes of Alpha-NADPH and Beta-NADPH. Beta-NADPH hase activity only. Beta-Nicotinamide adenine dinucleotide 2'-phosphate reduced tetrasodium salt or triphosphopyridine nucleotide reduced tetrasodium salt, also known as Coenzyme Ⅱ.

β-Nicotinamide adenine dinucleotide 2′-phosphate (NADP+) and β-Nicotinamide adenine dinucleotide 2′-phosphate, reduced (NADPH) comprise a coenzyme redox pair (NADP+:NADPH) involved in a wide range of enzyme catalyzed oxidation reduction reactions. The NADP+/NADPH redox pair facilitates electron transfer in anabolic reactions such as lipid and cholesterol biosynthesis and fatty acyl chain elongation. The NADP+/NADPH redox pair is used in a variety of antioxidation mechanism where it protects agains reactive oxidation species accumulation. NADPH is generated in vivio by the pentose phosphate pathway (PPP).
