	Males (n = 21)		Females (n = 20)
	Morning	Afternoon	Morning	Afternoon
	Intramyocellular acyl-carnitine-fatty acid concentration, μmol/g wet wt
Palmitoyl	0.068 ± 0.006	0.066 ± 0.006	0.069 ± 0.007	0.068 ± 0.006
Oleoyl	0.247 ± 0.030	0.224 ± 0.032	0.267 ± 0.028	0.251 ± 0.030
Palmitoyl + oleoyl	0.307 ± 0.031	0.277 ± 0.030	0.338 ± 0.039	0.319 ± 0.035
	imTG concentration, μmol/g wet wt
	1.12 ± 0.19†	1.09 ± 0.21†	2.77 ± 0.37	2.36 ± 0.31*

Values are means ± SE; n, no. of subjects. For women the afternoon time interval n = 19 for long-chain acyl-carnitine concentrations and for men the morning and afternoon time interval n = 20 for long-chain acyl-carnitine concentrations. imTG, intramyocellular triglyceride.

^*P < 0.05 between A.M. and P.M. sample;

^†P < 0.05, sex differences.
