responsible for the controlled energy transfer in heart muscle. In recent years, biochemistry
has been redefined to accommodate the increasing knowledge about the molecular events
of gene expression and the elements of intermediary metabolism. In light of the rapidly
occurring changes in the field of cardiac biochemistry, it seems useful to provide a brief …
