The change in the rate of muscle protein metabolism of rats from weaning to 90 days of age.
1. Protein synthesis, net deposition and breakdown was studied in the gastrocnemius muscles of growing rats between weaning and 90 days of age. 2. Fractional protein synthetic rates declined from 30.02% at 25 days to 7.41% at 90 days. 3. The rate of protein degradation follows a similar pattern to that of protein synthesis. A linear relationship was found. 4. The break in the growth curve between 30 and 31 days was also observed in protein metabolism.
