Pyrroloquinoline Quinone Disodium Salt

Pyrroloquinoline quinone (PQQ), also called methoxatin, is a redox cofactor and antioxidant.Produced by bacteria, it is found in soil and foods such as kiwifruit, as well as human breast milk.Enzymes using PQQ as a redox cofactor are called quinoproteins and play a variety of redox roles. Quinoprotein glucose dehydrogenase is used as a glucose sensor in bacteria. PQQ stimulates growth in bacteria. Eukaryote targets, including mammalian lactate dehydrogenase, are of more interest to health. It is suggested that PQQ taken as a dietary supplement could promote mitochondrial biogenesis via this pathway as well as PGC-1α.
