  1. Values are shown as means ± SE of three replicates. Means within the same row and not sharing a common superscript are significantly different (Ducans, P < 0.05); ns, no significant difference detected (P > 0.05).
  2. TC = total cholesterol; TG = triglycerides; FFA = free fatty acids; PC = phosphatidylcholine; PE = phosphatidylethanolamine; PI = phosphatidylinositol.
  3. 1% Wet weight.
  4. 2% Total lipid.
