Muzaffer Dukel, Ayse Gul Mutlu, Effects of Two Important Components Related with Mitochondria; CoQ10 and Acetyl-l-Carnitine in Antioxidant Enzyme Activities, Journal of Animal and Veterinary Advances, Volume 9,Issue 24, 2010, Pages 3109-3113, ISSN 1680-5593, javaa.2010.3109.3113, (https://makhillpublications.co/view-article.php?doi=javaa.2010.3109.3113) Abstract: For a number of years, coenzyme Q was known for its key role in mitochondrial bioenergetics; later studies demonstrated its presence in other subcellular fractions and in plasma and extensively investigated its antioxidant role. Coenzyme Q levels are also affected during aging and neurodegenerative diseases. Very few studies have been carried out to know effects of dietary coenzyme Q in wild type animals. Acetyl-l-carnitine facilitates the uptake of acetyl-CoA into the mitochondria during fatty acid oxidation. Acetylcarnitine supplementation has beneficial effects in elderly animals and humans. In current study, the effects of coenzyme Q10 and acetyl-l-carnitine in antioxidant enzyme activities and protein amounts were investigated. The use of coenzyme Q10 and acetyl-l-carnitine, two important component related with mitochondria as food supplements have similar effects in terms of antioxidant enzyme activities and protein amount of organism.
