Phosphatidylcholine (PC) species identified in the gastrocnemius. The lipid extract of the gastrocnemius excised from LDLR KO male mice fed a normal (NS; n = 7) or low-sodium diet (LS; n = 7) was subjected to a global lipidomic analysis performed with high-resolution mass spectrometry, ultra-high-performance liquid chromatography coupled to mass spectrometry coupled to ESI-Q-TOF-MS. PC species were separated in panels A–D according to their size, A) 0.0 to 0.15, B) 0.0 to 1.0, C) 0.0 to 1.5 and D) 0.0 to 15 μg/mg of protein. Values expressed as median (interquartile range) were compared by the Mann–Whitney test.
