heptanone/糖尿病

Total 4-heptanone is the sum of a beta-oxocarboxylic acid, 2-ethyl-3-oxohexanoic acid, and its decarboxylation product, 4-heptanone. The beta-oxocarboxylic acid is found in serum and in urine, and is detected by gas chromatography--mass spectrometry in the form of its methyl ester or its

BACKGROUND There is an ongoing discussion about the risks of di(2-ethylhexyl) phthalate (DEHP) exposure for the general population as well as for specific subgroups in various medical settings. Haemodialysis patients certainly belong to the group with the highest exposure taking into account the

Abnormally increased concentrations of the aliphatic alcohols ethanol, n-propanol, isobutanol, n-butanol and isopentanol and the ketones 4-heptanone and cyclohexanone in human urine reflect metabolic disorders related to diabetes mellitus. For the determination of these low-molecular-weight

Diabetes mellitus is a defect not only in glucose metabolism, but also in the metabolism of lipids and amino acids. Gas chromatographic and gas chromatographic--mass spectrometric profile analyses have contributed much to the understanding of the metabolic changes connected with this defect. Ketones
