Abstract
Summary
Studies were made on rates of catabolism and of tissue protein incorporation of intraperitoneally injected 75Se selenomethionine in cold-acclimated rats. The results of these studies indicate that both rates are increased in the cold. This could be indicative of an increased protein turnover rate in the cold-acclimated rat. Incorporation of labeled selenomethionine was faster in both kidney and liver. It is suggested that the rate of protein recycling may increase in the cold and that this could act as an intracellular respiratory stimulus by causing a more rapid conversion of ATP to ADP and to AMP.
