.... Plasma palmitate turnover rate ( 14 C) was unchanged from resting values in light work but was decreased by 40% (from 104 ± 16 to 63 ± 8 μmol/min) in heavy work. Heavy work was associated with falls in the plasma concentrations of all free fatty acids measured: palmitic acid (C 16:0 ), oleic acid (C 18:1...
