Ether-soluble acids were determined in the urine of dogs on basal diet supplemented with different kinds of natural fat. 0.1-0.4 gm. were recovered/100 gm. fat fed daily for 3 days. Similar results were obtained with fats containing only odd number, straight-chain fatty acids. Triglycerides of synthetic branched-chain fatty acids gave an increased Et₂O-soluble fraction in the urine. Et branched-chain fatty acids are inefficiently attacked in the body and are eliminated, whereas 2-, 3- and 5-methyldodecanoic acids are not excreted significantly. A number of branched-chain fatty acids were synthesized.
