title: High-performance liquid chromatographic determination of pyruvic acid and alpha-ketoglutaric acid in serum.
abstract: A high-performance liquid chromatographic determination of pyruvic acid and alpha-ketoglutaric acid in serum is described which is based on the formation of 2,4-dinitrophenylhydrazones. The syn-anti isomerization of the 2,4-dinitrophenylhydrazone of pyruvic acid is also discussed.
