Abstract:
This report describes the optimal conditions for the determination of bound choline in rat plasma. The method used was based on the liberation of choline by phospholipase D from phospholipids containing choline in plasma, followed by high-performance liquid chromatographic analysis. Normal concentrations of total, free and bound choline in rat plasma were found to be 1278.7 +/- 132.5, 11.5 +/- 2.2 and 1267.2 +/- 125.5 nmol/ml, respectively. The described procedure has the advantages of rapidity, specificity, excellent precision and the need for only a small amount of the sample.
