Fig. 4. Time course of changes in proportion of phospholipid classes and subclasses during warm acclimation. Values are means ± s.e.m. (N=4 for each acclimation state). Different superscript letters indicate values for a class or subclass that differ between acclimation states (ANOVA and a posteriori test, P0.05). Phospholipids are expressed as mol% of total moles of glycerophospholipids, calculated as indicated in Materials and methods. Abbreviations are defined in List of abbreviations.
