Abstract:
Here we describe a simple high-performance liquid chromatography (HPLC) procedure for the simultaneous detection and quantitation in standard solutions of 13 important metabolites of cellular energy metabolism, including 9 tricarboxylic acid (TCA) cycle components and 4 additional metabolites. The metabolites are detected by their absorbance at 210 nm. The procedure does not require prior derivatization, and an analysis can be carried out at ambient temperature within 15 min. The significance of the current work is that the current HPLC procedure should motivate the development of simplified TCA cycle enzyme assays, isotopomer analysis, and determination of selected TCA metabolite levels in plasma/tissues.

However, the stretching absorptions for the C=O bond vary depending on the structure of carboxylic acids. The C=O bond of the free carboxylic acids shows a higher stretching frequency, 1760 cm−1, while H-bonded carboxylic acids (dimers) exhibit stretching absorptions at a lower frequency,...
