To evaluate the usefulness of each derivatization procedure in the analysis of FAs liberated from the complex lipids, the hydrolysis of triacylglycerols (TGs) was performed. Stock solutions of TG slisted in Section 2.1 and ethyl nonadecanoate as internal standard were prepared in methylene chloride. Equal amounts (0.25 mg) of each compound were taken for the hydrolysis. The mixture was placed in a 4-mL screw capped glass vial and the solvent removed in a stream of nitrogen. Samples for the further silylation were hydrolyzed with 0.5 mL of 0.5 M KOH in 99.8% ethanol, while those for the synthesis of FAMEs were hydrolyzed with 0.5 mL of 0.5 M
