NADPH: Abbreviation for nicotinamide adenine dinucleotide phosphate (reduced form). NADP+ and other such cofactors (NAD+ and FAD+) are capable of accepting these electrons in a stable manner without forming harmful and overly reactive radicals. Each phosphate group joins a five-carbon ribose sugar. E.A. On the other hand, addition of hydrogen ion to NADP+ (nicotinamide adenine dinucleotide phosphate), produces NADPH. Reactive oxygen species (ROS) influence many physiological processes including host defense, hormone biosynthesis, fertilization, and cellular signaling. This nucleotide is made up of 5-carbon sugar (deoxyribose) attached to a nitrogen base (adenine) and a phosphate group. One of these in turn links to an adenine molecule, while the other links to a nicotinamide molecule. community of Class 11.
