Nicotinamide adenine dinucleotide phosphate, abbreviated NADP+ or, in older notation, TPN (triphosphopyridine nucleotide),
N 1575 (OTTO) Nicotinamide adenine dinucleotide phosphate disodium salt, 98% Cas 24292-60-2 - used in especially anaerobic reactions such as lipid and nucleic acid synthesis. NADP/NADPH is a coenzyme couple in various cytochrome P450 systems and oxidase/reductase reaction systems, such as the thioredoxin reductase/thioredoxin system.
