Abbreviations: SFA, saturated fatty acids; MUFA, monounsaturated fatty acids; PUFA, polyunsaturated fatty acids; UFA:SFA, unsaturated to saturated fatty acid ratio, calculated as described by Varona et al. [8]; TAG, triacylglycerols; DAG, diacylglycerols; MAG, monoacylglycerols; FFA, free fatty acids. 1 All samples were analyzed at least in duplicate. 2 Dietary treatments supplemented with 6% of palm oil (P), soybean acid oil (SA), soybean oil (S), or oil blends with 4% palm oil + 2% soybean acid oil (P4-SA2) or 2% palm oil + 4% soybean acid oil (P2-SA4). In all cases, fatty acids and lipid classes are expressed as peak area normalization (in %). 3 Minor fatty acids identified and quantified: C8:0, C10:0, C11:0, C12:0, C13:0, C14:1, C15:0, C15:1, C16:1, C17:0, C17:1, trans-C18:1, C18:3 n-6, C20:0, C20:1 n-9, C21:0, C20:2 n-6, C20:3 n-6, C20:4 n-6, C20:3 n-3, C20:5 n-3, C22:0, C22:1 n-9, C23:0, C22:2, C24:0, C22:6 n-3, C24:1.
