Abstract

The lipids of Crithidia fasciculata have been analysed. In addition to phosphatidylcholine, phosphatidylinositol and phosphatidylethanolamine both diphosphoinositide and triphosphoinositide were identified. Plasmalogens, lysophosphatides, phosphatidylserine and phosphonolipids were absent. Experiments with ³²P_i as precursor indicated that only the phosphoinositides were formed at a rate appreciably greater than that necessary to sustain new growth. The turnover of the polyphosphoinositides was very rapid and they were quantitatively decreased in cells at the end of the logarithmic phase of growth.
