Pyrroloquinoline quinone (PQQ) is a nutrient found in foods such as kiwi and spinach. It is known to have antioxidant properties and acts as a neuroprotectant.
PQQ is a coenzyme that acts as a prosthetic group to help enzymes do their jobs. It also serves as an antioxidant, shielding cells from free radical damage.
PQQ has also been shown to be a protective agent against lipid peroxidation. This is especially important for cells that contain mitochondria, the organelles in our bodies that produce energy. By protecting against oxidative damage, it helps the cells tolerate stress and maintain a healthy state.
PQQ is also thought to have anti-inflammatory effects, reducing inflammation in the brain. This may help to heal strokes and other brain injuries.
The benefits of PQQ have triggered many people to choose to take supplemental forms of this nutrient. Some claim to increase mental focus and longevity, while others claim to improve their memory and overall brain health. While these claims are interesting, the truth is that PQQ is not likely to be an enzymatic cofactor in humans.
However, it has been demonstrated that it is a natural substance that occurs in the body and that it can act as a molecule that binds to other proteins. It uses carbonyl groups and a schiff base to bind to these proteins, giving it the ability to do its job. In addition, it can help to modify these protein structures, thus giving it the ability to confer biolgical effects.
