Pyrroloquinoline quinone (PQQ) was discovered by J.G. Hauge as the third redox cofactor after nicotinamide and flavin in bacteria (although they hypothesised that it was naphthoquinone). Anthony and Zatman also found the unknown redox cofactor in alcohol dehydrogenase and named it methoxatin. In 1979, Salisbury and colleagues as well as Duine and colleagues extracted this prosthetic group from methanol dehydrogenase of methylotrophs and identified its molecular structure. Adachi and colleagues identified that PQQ was also found in Acetobacter.
These enzymes containing PQQ are called quinoproteins. Glucose dehydrogenase, one of the quinoproteins, is used as a glucose sensor. Subsequently, PQQ was found to stimulate growth in bacteria. In addition, antioxidant and neuro-protective effects were also found.
Its 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 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.| Item | Specification | Test Results |
