Abstract
The fatty acid composition of the liver and adipose tissue from fasting rats were examined by means of gas chromatography. It has been proved that each fatty acid which constitutes phopholipids or neutral fats of the liver and adipose tissue changes its content individually through the course of starvation. The fact suggests that the fatty acids of some kinds of the lipid seem likely to serve in a di fferent manner respectively as an energy source of the body.
