GC Helps Measure Polyunsaturated Fatty Acid Concentrations

In an article recently published in the British Journal of Nutrition, researchers used gas chromatography to determine the fatty acid concentrations of plasma phosphatidylcholine, triacylglycerol, NEFA and cholesteryl esters to test the hypothesis that gender-related differences in n-3 PUFA metabolism are reflected in the concentrations of n-3 PUFA in plasma lipids.

In an article recently published in the British Journal of Nutrition, researchers used gas chromatography to determine the fatty acid concentrations of plasma phosphatidylcholine, triacylglycerol, NEFA and cholesteryl esters to test the hypothesis that gender-related differences in n-3 PUFA metabolism are reflected in the concentrations of n-3 PUFA in plasma lipids. There were no significant differences between men and women in their consumption of protein, carbohydrate, total fat, alcohol, individual fatty acids and selected micronutrients. DHA concentration alone was significantly higher in plasma phosphatidylcholine, triacylglycerol, and NEFA ,  but not cholesteryl esters, in women compared with men. There were no significant differences between men and women in the concentrations of any other fatty acids measured.
