Pyrroloquinoline quinone (PQQ)

Pyrroloquinoline quinone disodium salt, a redox co-factor, is an anionic, redox-cycling orthoquinone. It is isolated from cultures of methylotropic bacteria and tissues ofmammals. It is also an essential nutrient for mammals and is important for immune function. Pyrroloquinoline quinone disodium salt, a sodium-based compound, exhibits notable antioxidant properties that have beenextensively researched. This compound plays a crucial role in shielding cells from oxidative harm and promotes the maintenance of mitochondrial membrane potential, a vital factor in ATP production. Moreover, PQQ disodium salt acts as a stimulant for key enzyme activities including glutathione peroxidase and glutathione reductase, while effectively preventing lipid peroxidation in human serum. Another remarkable attribute of this compound is its ability to inhibit radiation-induced cellular damage by safeguarding DNA strands from breakage.
