PPT-Oxidative Decarboxylation and Krebs Cycle

Objectives Oxidative Decarboxylation By the end of this lecture students are expected to Recognize the various fates of pyruvate Define the conversion of pyruvate to acetyl CoA Discuss the major regulatory mechanisms for PDH complex. ABSTRACT Oxidative stress is increased in diabetic patients since persistent hyperglycemia causes an increased production of oxygen free radicals through autoxidation of glucose and non enzymatic gl ycation of proteins Increased levels of the produc to proteins in . Drosophila . melanogaster. Trevor Short. Dr. David Brown, Faculty Advisor. Previous research has suggested that there is a link between an accumulation of oxidative damage and aging [1, 2, 3, 4]. Oxidative damage occurs as a result of the inability of the body to detoxify reactive oxygen species that are generated in the body as a byproduct of cellular respiration; These reactive oxygen species may go on to react with proteins in the body and inhibit their ability to function normally [4, 5]. When a reactive oxygen species interacts with a protein, amino acid residues are converted to carbonyl groups [4,5]. This experiment was performed in fruit flies.
