Gas-chromatographic-mass-spectrometric determination of urinary acid profiles of normal young adults. II. The effect of ethanol.

Urinary acid metabolic profiles of 26 healthy young adults who were maintained on a palatable standard diet for three days have been studied by combined gas chromatography-mass spectrometry. Means and standard deviations of the excretion rates of individual, identified acids were determined after the ingestion of ethanol and compared to basal values previously reported. A significant net effect of ethanol was demonstrated for only six of the acids studied: α- and β-hydroxybutyric, adipic, β-methyladipic, p -hydroxyphenylacetic, and 2,5-furandicarboxylic acids.
