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).
将通过生物合成在农场动物体内自然获得的14C标记的黄油、牛肉和羊肉脂肪,以及工业生产的油酸和葡萄糖引入白化雄性大鼠体内。通过实验测定了上述物质的吸收系数值、组织中的吸收和氧化速率、24小时内通过肺和皮肤以二氧化碳形式与空气一起以及与排泄物一起从生物体中消除的化合物比例。结果表明,葡萄糖代谢比脂肪代谢进行得更为强烈。不同食用脂肪的同化和消除速率取决于它们的组成(饱和脂肪酸与不饱和脂肪酸之间的比例)。
