The fatty acids 20:4n-4 and 24:5n-3 were quantified as < 0±1 μg / g RBC at all time points. The fatty acid 18:3n-6 and 22:1 were quantified as < 1±3 0 μg / g RBC at all time points. The fatty 15:0 and the fatty 20:1 was quantified as < 5±2 μg / g RBC and < 7±5 μg / g RBC, respectively at all time points. AA: arachidonic acid; LA: linoleic acid; PA: palmitic acid; SA: stearic acid
2 Mean < the limit of quantification for the method (LOQ 10 μg / g RBC).
3 Mean < the limit of detection for the method (LOD 3 μg / g RBC).
4 The method does not specify monounsaturated fatty acids.
