The Influence of Low Casein Diet on the Fatty Acid Composition of Rat Liver Mitochondrial Phosphatides

Abstract

Rats were divided into low casein diet and high casein diet fed groups, and the fatty acid composition of liver mitochondrial phosphatides was analyzed. It was found that in liver mitochondrial phosphatides the value of arachidonic acid decreased slightly, and that of the polyenoic fatty acid which was infered as 4, 7, 10, 13, 16-docosapentaenoic acid increased by low casein diet. The analysis was performed also on whole liver phosphatides. There was no great difference between the fatty acid composition of whole liver and liver mitochondrial phosphatides
