  • Early metabolic steps, including glycolysis and the activity of the pyruvate dehydrogenase complex, yield a two-carbon fragment called an acetyl group, which is linked to a large cofactor known as coenzyme A (or CoA). It is during the citric acid cycle that acetyl-CoA is oxidized to the waste product, carbon dioxide, along with the reduction of the cofactors NAD+ and ubiquinone

  • The increased level of reactive oxygen species (ROS) in living organisms over 60 years ago was implicated in the development of diseases and aging (Harman, 1956; 1983). This book is a collective scientific monograph presenting several important aspects related to ROS role in human and animal pathologies. In 1985, German scientist Helmut Sies first denoted oxidative stress concept, which immediately attracted attention of researchers in diverse basic fields. Several discoveries substantially stimulated the interest to ROS as ones related to many diseases.
