where FAismg of fatty acids per g of total lipids,AX is the peak area (fatty
acids), AIS is the peak area of the internal standard (IS) methyl ester of
tricosanoic acid (23:0), WIS is the IS weight (mg) added to the sample
(in mg), WX is the sample weight (in mg), CFX is the theoretical
correction factor, and CFAE is the conversion factor necessary to express
results asmg of fatty acids rather than asmethyl esters. The resultswere
converted from mg g−1 to g fatty acid 100 g−1 sample
