Pyrroloquinolinequinone (English Pyrroloquinolin quinones, shortly PQQ) or Methoxatin was discovered as important cofactor in metabolic processes only recently ( 2003). It is believed that it is PQQ is an important redox cofactor which can be classified as a new B vitamin such as niacin and riboflavin.

Description

In bacteria are now six known enzymes that have PQQ as cofactor. Mammals require PQQ as a cofactor of Dopaminhydroxylase. Plants also seem to produce at least two proteins that bind to PQQ.

Task / function

The overall function is not yet fully understood.

Occurrence

PQQ is found in various vegetables and meats.

Demand

The need for the people or the necessity of the administration of PQQ is not yet known, and still the subject of research. In mice, a PQQ - diets to poor skin, poor growth, reduced immune response and reduced reproductive behavior has led.
