[Phospholipid composition of human, dog and guinea pig adrenal cortex].

The phospholipid composition was studied in human and dog adrenal cortex and in guinea pig adrenal tissue. The major phospholipids of adrenal cortex were phosphatidylcholine and phosphatidylethanolamine whose ratio in the human, dog and guinea pig tissues was 2.16, 2.01, 1.61, respectively. Phosphatidylinositol, phosphatidylserine, sphingomyelin, diphosphatidylglycerin, lysophosphatidylcholine and lysophosphatidyl-ethanolamine were also found in adrenal cortex. A quantitative phospholipid composition of the human adrenal cortex was close to the dog one. The fatty acid composition of phosphatidylcholine from human and dog adrenal cortex was determined and some differences were shown.
