説明
NADPH is the reduced form of the coenzyme NADP+; used in anabolic reactions such as lipid and nucleic acid synthesis, which require NADPH as a reducing agent.
NADPH, Tetrasodium Salt is a A ubiquitous coenzyme that acts as an electron donor in many reactions utilizing dehydrogenase and reductase enzymes. It is generated by reduction of the electron acceptor NADP+. The following biological pathways involve NADPH: formation of carbohydrate from CO2 during photosynthesis, maintenance of high levels of reduced glutathione in erythrocytes, reduction of thioredoxin.
化学的特性
off-white to light yellow powder
使用
One of the biologically active forms of nicotinic acid. Differs from NAD by an additional phosphate group at the 2’position of the adenosine moiety. Serves as a coenzyme of hydrogenases and dehydroge
nases. Present in living cells primarily in the reduced form (NADPH) and is involved in synthetic reactions.
主な応用
NADPH is the reduced form of the electron acceptor nicotinamide adenine dinucleotide phosphate (NADP+) and acts as an electron donor in various biological reactions. In plants, NADPH is produced by ferredoxin-NADP+ reductase in the last step of the electron chain during photosynthesis. In animals is it predominantly produced by the pentose phosphate pathway, but is also generated by key mitochondrial enzymes. NADPH provides the reducing equivalents for biosynthetic reactions and the oxidation-reduction involved in protecting against the toxicity of reactive oxygen species.It is also used for the synthesis of lipids and cholesterol and during the process of fatty acid chain elongation.

生物活性
NADPH is an electron donor and a cofactor for many redox enzymes including nitric oxide synthetase.
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).
純化方法
Purification is mostly similar to that of NADH above. [Beilstein 26 III/IV 3671.]
