³¹P NMR spectra of the organic extracts from detergent-solubilised sperm phospholipids subsequent to flotation on a sucrose gradient by ultracentrifugation. Assignments are given in the individual traces and were made by comparison with the chemical shifts of samples of known compositions. Please note that all spectra are scaled in the way that the resonance of the standard (PA (14:0/14:0) at 3.2 ppm) possesses the same intensity. Please also note the enrichment of PI and SM in the Triton X-100 samples.
