WebJun 12, 2012 · In an attempt to provide further verification of the true FFA content of the oil, the sample was analyzed by LC–MS. The LC–MS data are in reasonably good agreement with the selective esterification data for the total amount of FFA in the starting sample (F = 0.29) as well as the total amount of spike added (F = 1.51). WebOct 2, 2014 · Abstract. Objective: Although elevated free fatty acid (FFA) levels in obesity have been considered to be of importance for insulin resistance, a recent meta-analysis suggested normal FFA levels in obese subjects.We investigated fasting circulating FFA and glycerol levels in a large cohort of non-obese and obese subjects. Methods: Subjects …
