Abstract
The lipids of the interscapular brown fat of the white mouse have been examined by means of silicic acid column chromatography and quantitative paper chromatography. The fatty acid composition of the glycerides and phosphatides was determined by gas chromatography. Comparative studies of mouse brown and white fat are presented.The fatty acid composition of the glycerides of the two tissues was similar at all ages examined. In both tissues, the average chain length of the glyceride fatty acids increased with age. The glycerides of brown fat at all ages contained less palmitoleic acid and more stearic acid than the corresponding white fat.The adult brown fat contained more polyglycerophosphatide and less sphingomyelin than white fat. The fatty acid composition of the lecithins of the two tissues was very similar. The similarity of brown fat and liver phosphatides is discussed.Keywords
