Benefits of PQQ (Pyrroloquinoline quinone) PQQ supports mitochondrial health and cellular energy production, and protects the body from oxidative stress. Most notably, PQQ stimulates the spontaneous growth of new mitochondria in aging cells, and activates genes that govern mitochondrial reproduction, protection, and repair.
The levels of free pyrroloquinoline quinone (PQQ) in various foods were examined by the use of gas chromatography-mass spectrometry.PQQ was extracted from the samples, after addition of [U-13C]PQQ as internal standard, with n-butanol and Sep-Pak C18 cartridges.After derivatization of PQQ with phenyltrimethylammonium hydroxide, molecular peaks at m/z 448 and 462 were used for detection of PQQ and [U-13C]PQQ respectively, by selected ion monitoring.
