Lipids were isolated by TLC, and fatty acid composition was determined by GC of methyl esters. Data are given in mol% and represent means of three experiments. SD was always <2.0 mol%. Fatty acids are abbreviated as X:Y, where X and Y depict the number of carbon atoms and double bonds, respectively.
