Abstract

The half-life (T1/2) of the proteins and cytochorme c of rabbit myocardial mitochondria was determined by the use of glycin-1-C14 and aminolevulinic acid-H3, respectively, as precursors. T1/2 of cytochrome c calculated from the dynamics of the decrease in content of the label in the course of several weeks of investigation, was 11.8 days and T1/2 of the mitochondrial proteins 14.4 days. The degree of reutilization of glycine-C14 in structural metabolism was about 20%. No change was found in the rate of degradation of the mitochondria in rabbits with allergic myocardial damage.
