Results are expressed as mol%. Values are means ± s.e.m(N=4 for each acclimation state). Different superscript letters indicate values that differ between acclimation states (ANOVA and a posteriori tests, P≤0.05).
Diacy1PC refer to fatty acids at both sn-1 and sn-2 positions of the diacyl form.
PlsmPC refer to sn-2 fatty acyl chains of the plasmalogen form. The total percent was adjusted to 50% to take into account the absence of the alkenyl chains of the sn-1 position hydrolyzed by the acid mobile phase as described in Materials and methods.
Others: total of 18 fatty acids detectable (15:0, 17:0, 16:1n-5, 18:1n-5,18:3n-3, 18:3n-6, 20:1n-11, 20:1n-7, 20:2n-6, 20:3n-6, 20:4n-3, 21:5n-3,22:1n-11, 22:1n-9, 24:1n-11, 24:1n-9, 24:5n-3, 24:6n-3), none of which were more than 1.0% in any subclass.
