| Abstract: | The influence of carbohydrate-free and high-fatty (82% calorific value) ration on the content and turnover of proteins and lipids in the liver and perirenal fatty tissue was studied in experiments in vivo, in male Wistar rats (n = 23) with initial body weight (bw) 200 +/- 10 g. One month after the feeding with the ration studied bw of rats given carbohydrate-free diets did not differ from that of the control animals. The protein content was decreased and its turnover slowed down in hepatocytes of rats given carbohydrate-free ration. No significant changes were detected in the lipid content and turnover in hepatocytes. No changes were recorded in the protein content and turnover in the rat fatty tissue; however, significant changes were observed in the lipid turnover. They were manifest in an increased use of ramified aminoacid metabolites in lipid synthesis, and in speeding up the lipid turnover. |
