Abstract

For up to 3 weeks 10 male rats weighing about 300 g were given diets which had 20% protein or were free from protein but supplied similar amounts of energy. The rats were killed at intervals; the last 2 were given L-[U-14C]tyrosine by infusion 4 h before they were killed. The deprived rats showed restricted amino acid oxidation and a decreased rate of protein synthesis. Amino acid oxidation continued by an uneven loss of proteins from the tissues. In muscle the composition and relative synthesis rate of the constituent proteins were not affected. Liver and kidney, compared with other tissues tended to maintain a relatively high rate of protein turnover. (Abstract retrieved from CAB Abstracts by CABI’s permission)
