Gas liquid chromatographic studies of [1-14C] palmitate uptake by the perfused guinea-pig heart.
In addition to the uptake of palmitate by the isolated perfused guinea-pig heart, there was a substantial release of longer chain fatty acids into the perfusate amounting to about 50% of the uptake of palmitate. Both the uptake of palmitate and the release of other fatty acids was diminished in the presence of 95% N2. The specific activity of myocardial palmitate was increased under 95% N2. No significant difference in the distribution of radioactivity between the different myocardial fatty acids occurred between 95% O2 and 95% N2.
