Skeletal muscle sphingolipid species. Lipid abundance in the quadriceps of WT (white bar) and BLAJ (black bar) mice presented as absolute units relative to protein mass. A: Cer. B: Hex1Cer. C: Hex2Cer. D: Hex3Cer. E: GM3. F: SM. Data are means ± SEMs, n = 12 WT and n = 8 BLAJ mice. *P < 0.05 as assessed by two-tailed unpaired t-test. Cer, ceramide; GM3, GM3 ganglioside; Hex1Cer, monohexosylceramide; Hex2Cer, dihexosylceramide; Hex3Cer, trihexosylceramide.
