Incorporation of lactic acid into cellular lipids. Myotubes were incubated with [14C(U)]lactic acid (1 µCi/ml, 20 mM) for the last 24 h of the differentiation period before total cell lipids were extracted and separated by thin layer chromatography. Incorporation into cellular lipids calculated as % of total lipid content (57.9 ± 29.5 nmol/mg protein). Data are presented as means ± SEM (n = 3). PL, phospholipids; DAG, diacylglycerol; FFA, free fatty acids; TAG, triacylglycerol; CE, cholesteryl ester. *Statistically significant vs. basal (p < 0.05, paired Student’s t-test).
