Cardiolipin Is Required For Optimal Acetyl-Coa Metabolism, Vaishnavi Raja

Wayne State University Dissertations

The phospholipid cardiolipin (CL) is crucial for many cellular functions and signaling pathways, both inside and outside of mitochondria. My thesis focuses on the role of CL in energy metabolism. Many reactions of electron transport and oxidative phosphorylation, the transport of metabolites needed for these processes, and the stabilization of electron transport chain supercomplexes, require CL. Recent studies indicate that CL is required for the synthesis of iron-sulfur (Fe-S) co-factors, which are essential for numerous metabolic pathways. Activation of carnitine-acetylcarnitine translocase, which transports acetyl-CoA into the mitochondria, is CL dependent. The presence of substantial amounts of CL in the peroxisomal …
