03 Pyrroloquinoline quinone General Description
Pyrroloquinoline quinone (PQQ), also called methoxatin, is a redox cofactor. It is found in soil and foods such as kiwifruit, as well as human breast milk. Enzymes containing Pyrroloquinoline quinone powder are called quinoproteins. Glucose dehydrogenase, one of the quinoproteins, is used as a glucose sensor. Pyrroloquinoline quinone powder stimulates growth in bacteria.
Pyrroloquinoline quinone powder was found to improve not only immediate memory, but also other higher brain functions such as spatial awareness. The effects of Pyrroloquinoline quinone powder were enhanced when the substance was used with CoQ10. The key benfits of Pyrroloquinoline quinone powder include mitochondrial health, brain support, and cardiovascular health.
04 Pyrroloquinoline quinone History
Pyrroloquinoline quinone powder was discovered by J.G. Hauge as the third redox cofactor after nicotinamide and flavin in bacteria (although he hypothesised that it was naphthoquinone). Anthony and Zatman also found the unknown redox cofactor in alcohol dehydrogenase. 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 discovered that Pyrroloquinoline quinone was also found in Acetobacter.
