Distribution of Selected TAG Molecular Species.

Distribution of selected TAG molecular species in mol %. Ion counts within ± 0.02 m/z units of each sodiated [M + Na]⁺ (labeled on figure) and potassiated [M + K]⁺ monoisotopic masses are normalized to the total TAG ion signals on each pixel. A red-green linear color scale is used with maximum mol % value corresponding to 35% of total TAG for all images. See Supplemental Table 1 online for all TAG species identified and m/z analysis for each species. Bar = 1 mm.
