Description

Pyrroloquinoline quinone disodium salt is a water-soluble quinone compound that has a strong anti-oxidant capacity.

Uses

Pyrroloquinoline quinone disodium salt can act as an antioxidant and there is strong evidence that PQQ may play an important role in important pathways of cell signaling. PQQ plays a variety of physiological roles, such as promoting growth and reproduction and providing neurological and cardiovascular protection.

Source

Methoxatin/pyrroloquinoline quinone (PQQ) is mostly seen in plants, few bacteria and single cell eukaryotes, like yeast. It is mainly obtained from methylotrophic bacteria. PQQ may also present in the tissues of mammals.

Biochem/physiol Actions

In bacteria, pyrroloquinoline quinone (PQQ) is used as a redox cycling cofactor. It acts as a cofactor (prosthetic group) for enzyme-catalyzed redox reactions of glucose and methanol dehydrogenase(s). PQQ is used in liposomes to establish a simple homogeneous assay for the detection of membrane permeabilization by antimicrobial peptides and synthetic copolymers. In bovine plasma amine oxidase, methoxatin may acts as the cofactor.
