[PC38:6+Na]+ (m/z 828.5515) obtained from mouse lung tissue collected 6 h after administration of D9-
choline and U13C-DPPC–containing CHF5633. Parts-per-million (ppm) mass errors are indicated in
parentheses. (c) Magnification of the boxed region in (a) with selected bronchiolar regions outlined in
white boxes. (d) The corresponding H&E-stained tissue section with the same selected bronchiolar
regions outlined in black boxes. These data demonstrate the co-localisation of the polyunsaturated lipids
PC36:4 and PC38:6 with the bronchiolar regions of the lung. All MSI images were visualised using
total ion current normalisation and hotspot removal (high quantile = 99%). |

PA(15:0/24:0) is a phosphatidic acid. It is a glycerophospholipid in which a phosphate moiety occupies a glycerol substitution site. As is the case with diacylglycerols, phosphatidic acids can have many different combinations of fatty acids of varying lengths and saturation attached at the C-1 and C-2 positions. Fatty acids containing 16, 18 and 20 carbons are the most common. PA(15:0/24:0), in particular, consists of one chain of pentadecanoic acid at the C-1 position and one chain of lignoceric acid at the C-2 position. Phosphatidic acids are quite rare but are extremely important as intermediates in the biosynthesis of triacylglycerols and phospholipids.
