Pyrroloquinoline quinone (PQQ) is a redox cofactor found in various foods, including human breast milk. It is classified as a quinone molecule, indicating its ability to participate in oxidation-reduction reactions. While not currently recognized as a vitamin, PQQ shares some functional similarities with B vitamins due to its involvement in enzymatic processes. It was first identified as a growth factor for bacteria and later found in higher organisms. PQQ is concentrated in mitochondria, the organelles responsible for cellular energy production. Research has focused on its potential roles in antioxidant activity, mitochondrial biogenesis (the formation of new mitochondria), and cellular signaling pathways. (Sourced from PubChem, NIH ODS)
