title: The occurrence of substituted 3-methyl-3-hydroxyglutaric acids in urine in propionic acidaemia and in beta-ketothiolase deficiency.
abstract: THe urine of two patients with propionic acidaemia contained 3-ethyl-3-hydroxyglutaric acid which has a propionyl residue in place of one of the acetyl residues of the normal metabolite 3-methyl-3-hydroxyglutaric acid. Related compounds, 2,3-dimethyl-3-hydroxyglutaric acid, 2-methyl-3-ethyl-3-hydroxyglutaric acid and 2,3,4-trimethyl-3-hydroxyglutaric acid, could not be detected in propionic acidaemia urine, but 2,3-dimethyl-3-hydroxyglutaric acid was excreted by a patient with beta-ketothiolase deficiency.
