A method for the measurement of organic acids in human plasma is presented. The
analytical procedure consists of plasma protein precipitation with acetonitrile, acid extraction
by chromatography through a DEAE-cellulose column eluted with 100 mM perchloric acid,
HPLC by cation-exchange column Aminex HPX-87 eluted with 6.5 mM sulfuric acid. Adipic,
3-hydroxy-3-methylglutaric, 2-oxoglutaric, and citric acids were determined in the plasma of

A method for the measurement of organic acids in human plasma is presented. The analytical procedure consists of plasma protein precipitation with acetonitrile, acid extraction by chromatography through a DEAE-cellulose column eluted with 100 mM perchloric acid, HPLC by cation-exchange column Aminex HPX-87 eluted with 6.5 mM sulfuric acid. Adipic, 3-hydroxy-3-methylglutaric, 2-oxoglutaric, and citric acids were determined in the plasma of diabetic patients. The concentrations of all the measured acids, but particularly those of adipic and 3-hydroxy-3-methylglutaric acids, were significantly higher than those of healthy controls. These results suggest that in diabetics the ω-oxidation of fatty acids is enhanced.
