NADPH tetrasodium salt

NADPH, Tetrasodium Salt is a ubiquitous cofactor and biological reducing agent that acts as an electron donor in many biological reactions. It is generated by reduction of the electron acceptor NADP⁺, and is very similar to another cofactor, NADH, which lacks a phosphate group at position 2' of the ribose moiety on the adenine half of the dinucleotide. This compound is involved in many pertinent biochemical pathways, including: formation of carbohydrate from CO₂ during photosynthesis, maintenance of high levels of reduced glutathione in erythrocytes, reduction of thioredoxin, and formation of free radicals in immune cells which are used to destroy pathogens - aka the respiratory burst.
