2.4. Conversion of 14C-glycine to 14C-lipids
For determination of 14C-lipid synthesis, muscle slices (50 mg) were incubated at 25 °C with constant shaking with 500 μL of SFC pH 7.8, equilibrated with O2:CO2 (95:5, v/v) in the presence of 0.2 μCi of [U-14C]-glycine (104 mCi/mmol Amersham, International), plus 5 mM of unlabeled glycine, for 60 min
