Abstract

Very little information is available as to the composition of the unsaturated fatty acids of animal tissues, especially as regards the location of the double bonds. This is a report of preliminary experiments on the fatty acids of beef heart muscle and liver. The unsaturated acids were separated by two methods, crystallization of the bromine derivatives and fractional distillation of the methyl esters. The method of Armstrong and Hilditch was used for the oxidation of the unsaturated acids and the results obtained up to this time indicate that the first double bond nearest the carboxyl group is in the 9:10 position. Azelaic acid is the only dibasic acid which has been separated from the oxidation products. Evidence of the formation of other dibasic acids has been obtained, but these have not been identified as yet.
