Summation

Coenzyme A (CoA) is a ubiquitous cofactor that functions as an acyl group carrier in diverse processes including fatty acid metabolism and the TCA cycle (Lipmann 1953). It is synthesized from the vitamin pantothenate in a sequence of five reactions (Daugherty et al. 2002; Leonardi et al. 2005; Robishaw and Neely 1985). These reactions all occur in the cytosol or the mitochondrial intermembrane space (Leonardi et al. 2005). A recently described transport protein appears to mediate the uptake of Coenzyme A into the mitochondrial matrix (Prohl et al. 2001).
