DescriptionECHEMI Editorial ReferenceSolid
Pyrroloquinoline quinone is a pyrroloquinoline having oxo groups at the 4- and 5-positions and carboxy groups at the 2-, 7- and 9-positions. It has a role as a water-soluble vitamin (role), a cofactor, an antioxidant and an anti-inflammatory agent. It is a member of orthoquinones, a tricarboxylic acid and a pyrroloquinoline cofactor. It is a conjugate acid of a pyrroloquinoline quinone(3-).|A pyrrolo-quinoline having two adjacent keto-groups at the 4 and 5 positions and three acidic carboxyl groups. It is a coenzyme of some DEHYDROGENASES.
Pyrroloquinoline quinone (PQQ) is a novel biofactor for which a proposition can be made for physiological importance. PQQ was first recognized as an enzyme cofactor in bacteria. It has recently been tentatively identified as a component of interstellar dust. Thus, PQQ may have been present throughout early biological conception and evolution. PQQ is also a potent plant growth factor. Consequently, for animals and humans, there has been constant exposure to PQQ. In animals, PQQ is reported to participate in a range of biological functions with apparent survival benefits (e.g., improved neonatal growth and reproductive performance). There are also benefits from PQQ supplementation related to cognitive, immune, and antioxidant functions, as well as protection from cardiac and neurological ischemic events. Although PQQ is not currently viewed as a vitamin, its involvement in cell signaling pathways, particularly those important to mitochondriogenesis in experimental animal models, may eventually provide a rationale for defining PQQ as vital to life. For humans, such evidence suggests there may be similar parallels or benefits from improving PQQ status.

PQQ is pyrroloquinoline quinone. It is sometimes called methoxatin, pyrroloquinoline quinone disodium salt, and a longevity vitamin. It is a compound made by bacteria and is found in fruits and vegetables.PQQ in bacteria helps them digest alcohol and sugar, which makes energy. This energy helps them survive and grow. Animals and plants don’t use PQQ the same way that bacteria do, but it is a growth factor that helps plants and animals grow. It also seems to help them tolerate stress.Basic Info-
