Description

Biochem/physiol Actions

PQQ is present in nanomolar quantities in most foods and in most animal tissuse. It promotes growth, mitochondrial function, and development in vivo and stimulates cell proliferation and viability in culture. It is a potent antioxidant that scavenges superoxide and peroxinitrite. It is neuroprotectant against 6-hydroxydopamine-induced and hypoxia/ischemia-induced neurotoxicity. PQQ conjugates to α-synuclein in vitro, inhibiting the formation of amyloid fibrils.

General description

Novel o-quinone coenzyme found in bacterial dehydrogenases and oxidases.
