Pyrroloquinoline quinone, PQQ for short, is a new coenzyme different from nicotinamide nucleotides (NAD + and NADP +) and flavin nucleotides (FAD and FMN). PQQ is a cofactor of dehydrogenase redox reaction in bacteria.
In 1979, Durine and other researchers separated the coenzyme from bacteria, and then its structure was confirmed as 4,5- dihydro-4,5-dioxo-1-hydropyrrolo (2,3-f) quinoline-2,7,9-tricarboxylic acid.
PQQ is widely distributed in nature from microorganisms to animal tissues, but it is considered that only Gram- negative bacteria can synthesize PQQ, Human beings can only obtain PQQ through diet to meet the needs of the body, and the intestinal flora cannot synthesize
PQQ. Therefore, exogenous PQQ intake is very important to maintain the needs of human and animal tissues and the stability of intestinal flora.
