The scientific name of the PQQ pyrroloquinoline quinone (PQQ) pyrroloquinoline quinone is a new prosthetic group,  is the second flavin nucleotides (FMN, FAD) and nicotinamide nucleotide (MAD NADP) in the membrane boundfound in the bacterial dehydrogenase third cofactor,the world's medical profession called fourteenth vitamins. 

The compound was first isolated from bacteria out, and then moving the plants have also been found.

 its chemical name is 4,5 - dihydro-4 ,5 - dioxide -1 - pyrrolo (2,3 f) The quinone -2,7,9-tricarboxylic acid, also known as methaxatin.

PQQ as a novel watersoluble vitamins, the oxidoreductase is a cofactor, it is very rare, exist in a number of microbial, plant and animal tissues, not only involved in the catalytic-vivo redox reaction, but also has some special biological activity and physiological functions (such as shortening the stench Acetobacter [the Acetobacter rancens] and 

Beer yeast [Saccharomyces cerevisiae] retardation period, to stimulate early germination of tobacco seeds, prevention and treatment of certain diseases such as biological function). 

Trace amounts of PQQ will be able to improve the living tissue metabolism and growth performance, extremely valuable.

1 An overall improvement in energy levels

2 Improved cognitive function and memory 

3 Reduction in mitochondrial degradation

4 Increased skin elasticity

5 Neuro-protectant

6 Cardio-protectant

7 Enhanced nerve growth

• As a powerful antioxidant, PQQ protects and increases the functionality of existing mitochondria  -Slowing mitochondrial aging.

 • PQQ also promotes the generation of new mitochondria (Mitochondrial Biogenesis).-Increased mitochondria = increased energy production.

• PQQ stimulates production of Nerve Growth Factor (NGF).-NGF triggers growth of nerve cells to repair damaged nerves from stroke or other injury.
