Abstract
Rats were divided into high protein diet and low protein diet fed groups. Their livers were removed, homogenized, and fractionated into nuclei, mitochondria, microsome and supernatant fraction.
Amount of total- and phospho-lipids in each fraction was measured, and simultaneously, total nitrogen was measured. Then, the ratio of total- and phospho-lipids to nitrogen was calculated. The influence of low protein diet on this calculated value was seen in the mitochondrial and supernatant fraction, but was not recognized in other fractions.
The relationship between this phenomenon and energy efficiency of diets was discussed.
