Fig. 6. Responses of P. lineatus to the PC profile. (A) HPLC separation of
PC components into two fractions, Fr. 1 and Fr. 2. x-axis, retention
time; y-axis, signal intensity. (B) Response of P. lineatus
to Fr. 1, Fr. 2, and the recombined PC fraction (Mix). Values are means
± s.e.m. Asterisks, P<0.05. (C) Responses of P.
lineatus to PC, the composition of which was modified by the addition of
synthetic PCs SPC1 (16:0-22:6)
[1-palmitoyl-2-(4,7,10,13,16,19-(E)-docosahexaenoyl)-sn-glycero-3-phosphocholine]
and SPC2 (16:0-20:4)
[1-hexadecanoyl-2-(5,8,11,14-(E)-eicosatetraenoyl)-sn-glycero-3-phosphocholine].
The PC activity was gradually affected depending on the concentration of SPC.
Values are means ± s.e.m. Asterisks, P<0.05. Ctrl,
