Assessment of oxidizable molecular species of PS in naive and LA-supplemented HL60 cells. (a) Quantitative assessment of PS molecular species (sn1/sn2) in control naive, and LA-supplemented HL60 cells. Note the increase in the content of C18 : 1/C18 : 2 (m/z 784) and C18 : 0/C18 : 2+C18 : 1/C18 : 1 (m/z 786) PS molecular species and a decrease in C16 : 0/C18 : 1 (m/z 760) and C18 : 0/C18 : 1 (m/z 788) species after supplementation of cells with LA were detected. (b) Selected reaction monitoring was used to resolve the m/z 786 peak and determine the relative abundance of C18 : 1/C18 : 1 (solid bars) and C18 : 0/C18 : 2 (hatched bars) PS species. *P<0.05, n=3
