Table 2.

Composition of PE species of the DRM fraction and the total cell extract of MDCK cells (d), McArdle cells (e) and sperm cells (f). Numbers of identified PE species refer to peaks indicated in chromatograms D, E and F of Fig. 6. Mean values expressed in mole% ± SD (n = 3) are indicated. The unsaturation and chain length of the sn-1 and sn-2 substituents are expressed as the average number of double bonds or carbon atoms per fatty acyl residue (taking abundance of species into account). Asterisks indicate significant differences between DRMs and whole cell extracts in a Students t-test. * P < 0.05, ** P < 0.01 and *** P < 0.001. Red indicates a significant depletion of a lipid component in the DRM when compared to the relative amount detected in whole cells, green indicates a significant accumulation of a lipid component in the DRM when compared to whole cells (for colors P < 0.05)
