nicotinamide adenine dinucleotide phosphate
Quick Summary
Nicotinamide adenine dinucleotide phosphate (NADP) is a coenzyme found in red blood cells that plays a role in intermediary metabolism. It is similar in function to NAD (nicotinamide adenine dinucleotide) but often acts on different metabolites. NADP is a phosphorylated derivative of NAD.12
NADP is involved in cellular respiration, a process where organisms combine oxygen with food molecules to convert chemical energy into life-sustaining activities. During glycolysis, a stage of cellular respiration, NAD+ is converted to NADH. In photosynthesis, within chloroplasts, light energy is used to energize electrons, which are then transferred down an electron-transport chain. This process ultimately leads to the joining of a proton with NADP+ to form NADPH. NADPH is the reduced form of NADP and acts as a high-energy electron donor, along with ATP, to fuel carbohydrate production in plant cells.324

photosynthesisOverall reaction of photosynthesisof ATP and the electron-donor-reduced nicotine adenine dinucleotide phosphate (NADPH). During the dark reactions, the ATP and NADPH formed in the light-capturing reactions are used to reduce carbon dioxide to organic carbon compounds. This assimilation of inorganic carbon into organic compounds is called carbon fixation.
