Pyrroloquinoline quinone （PQQ）Applications
- Biomedical field
Pyrroloquinoline quinone (PQQ) exhibits significant antioxidant, anti-inflammatory and neuroprotective properties in biomedicine. It improves energy metabolism by activating mitochondrial biogenesis (increasing mitochondrial density by 20-30%) and is used to treat neurodegenerative diseases (such as Alzheimer’s disease), liver fibrosis and diabetic complications. - Food and nutritional supplements
PQQ is widely added to functional beverages, sports nutrition and anti-aging products. It delays food oxidation by scavenging free radicals (its antioxidant capacity is 100 times that of vitamin C), while reducing lactic acid accumulation after exercise and improving endurance. - Agriculture and Animal Husbandry
In agriculture, PQQ as a plant growth regulator (concentration 0.1-0.5 ppm) can enhance crop resistance and increase yield; in animal husbandry, adding it to feed (0.1-0.2 mg/kg) can improve poultry reproduction, enhance animal immunity and reduce mortality. It reduces dependence on antibiotics by regulating the balance of intestinal flora. - Industrial and Chemical Applications
PQQ is used as a dye intermediate in textile and ink production, with high color fastness and low toxicity. Its derivatives play a key role in photosensitive materials, plastic antioxidants and rubber vulcanization accelerators. At the same time, it participates in redox reactions as an organic catalyst, promoting the development of green chemical synthesis technology.
