| Abstract: | 1. Lipid composition of Trypanosoma cruzi epimastigote form in culture consist of 35% of phospholipids and 65% of neutral lipids. 2. Among the phospholipids, phosphatidylcholine is the more abundant (44%), followed by phosphatidylethanolamine (28%), phosphatidylinositol (12%), sphingomyelin (4%), and smaller amounts of cardiolipin, phosphatidic acid, lysolecithin, phosphatidylserine (traces), and an unidentified phospholipid (3%). 3. Pulse labeling with 32P showed highest specific incorporation in phosphatidylethanolamine, followed by phosphatidylinositol and phosphatidylcholine, suggesting a more active role for phosphatidylethanolamine in these organisms. |
