Mean proportion of neutral lipid fatty acids.

Mean proportion is given on a mass basis, ± s.e. The mean proportion of each individual fatty acid was calculated as a percentage of the total amount of fatty acid methyl esters (TFAMEs). (Un)saturation indices are as follows: ∑SFAs = sum of saturated fatty acids, ∑MUFAs = sum of monounsaturated fatty acids, U/S = ratio of unsaturated to saturated fatty acids, ACL = average acyl chain length and PI = peroxidation index (see the materials and methods section for details).Mean proportion of neutral lipid fatty acids.
