[Processes of 14C-labeled glucose and dietary fat assimilation and metabolism]. / Izuchenie protsessov usvoeniia i obmena gliukozy i pishchevykh zhirov, mechennykh 14C

14C-labeled butter, beef and mutton fats, naturally obtained in farm animals through biosynthesis, as well as oleic acid and glucose, put out by the industry, were introduced to albino male-rats. The values of absorption coefficients for the said substances, the rates of absorption and oxidation in tissues, the proportion of compounds eliminated from the organism in 24 hours together with the air in the form of CO2 through the lungs and skin and together with excreta were determined experimentally. It is shown that the glucose metabolism proceeds much more intensively than does the fat metabolism. The rate of assimilation and elimination of different edible fats depends upon their composition (ratio between saturated and unsaturated fatty acids).
