Biological Activity

[Description]:

Pyrroloquinoline quinone (PQQ), a redox co-factor, is an anionic, redox-cycling orthoquinone. Pyrroloquinoline quinone is isolated from cultures of methylotropic bacteria and tissues of mammals. Pyrroloquinoline quinone is an essential nutrient for mammals and is important for immune function[1][2].

Human Endogenous Metabolite

[In Vitro]

Mouse pups born to and nursing from Pyrroloquinoline quinone (PQQ)-deprived dams have a compromised immune response as well as alopecia, a hunched posture, and a susceptibility to aortic aneurysms[2].
