PQQ as a novel water-soluble 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.
