Abstract
1. Lipids from the whole adrenal glands of the ox and the African buffalo (Syncerus caffer) were extracted and fractionated into neutral and phospholipids. Both species revealed the presence of considerable quantities of cholesterol but only very small quantities of cholesteryl esters. 2. Fatty acids from various fractions of bovine and buffalo adrenal glands were investigated by gas-chromatography. They showed a remarkably low content of higher unsaturated fatty acids and a very high content of stearic acid. 3. Mitochondrial and microsomal fractions were isolated from the adrenal glands of the impala antelope (Aepyceros melampus), their lipids extracted, analyzed and compared with the composition of the mitochondrial lipids from bovine adrenal glands. 4. Subcellular fractions of the bovine and impala adrenal glands contain only very small quantities of esterified cholesterol. Most of the lipid fractions were characterized by the absence of adrenic acid (C22:4 omega 6) and a low content of arachidonic acid.
