Human Endogenous Metabolite
In Vitro Both CoQ9 and CoQ10 are equally cardioprotective, as evidenced by their abilities to improve left ventricular performance and to reduce myocardial infarct size and cardiomyocyte apoptosis. HPLC analysis reveals that a substantial portion of CoQ9 has been converted into CoQ10[1]. CoQ10 and CoQ9 are components of themitochondrial respiratory chain in mammals and can regulate some mitochondrial proteins/functions. Soybean, corn, and rapeseed oils are very rich sources of CoQ10, whereas CoQ9 has been found in high concentrations in corn oil[2].
In Vivo The lack of a functional CoQ9 protein in homozygous CoQ9 mutant (CoQ9(X/X)) mice causes a severe reduction in the CoQ7 protein and a widespread CoQ deficiency and accumulation of demethoxyubiquinone. The deficit in CoQ induces a brain-specific impairment of mitochondrial bioenergetics performance, a reduction in respiratory control ratio, ATP levels and ATP/ADP ratio and specific loss of respiratory complex I. These effects lead to neuronal death and demyelinization with severe vacuolization and astrogliosis in the brain of CoQ9 (X/X) mice that consequently die between 3 and 6 months of age[3].
