Description
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).
Purity
Determined by increase in absorbance at 340nm on enzymatic reduction with G6PDH* at pH 10 (More than 95%) *G6PDH = Glucose-6-phosphate dehydrogenase (yeast) (EC 1.1.1.49.)
Structure
C21H27N7O17P3.K
Specificity
Water content: < 8% by Karl Fischer
Storage
Keep tightly stoppered in the dark below 5°C. Moisture will reduce the purity. For prolonged storage, keep below-20°C.
Synonyms
β-Nicotinamide-Adenine Dinucleotide Phosphate, Oxidized Form (β-NADP-K); β-Nicotinamide-Adenine Dinucleotide Phosphate; β-NADP-K
