Descrizione generale

4-Heptanone is a volatile constituent of human urine.

Applicazioni

4-Heptanone was used in the quantitative analysis of 4-Heptanone in urine samples by gas chromatography-mass spectrometry. 4-Heptanone was used to evaluate the enantioselectivity and catalytic ability of the 4-hydroxyacetophenone monooxygenase from Pseudomonas fluorescens ACB.

Azioni biochim/fisiol

4-Heptanone is the major β-oxidation metabolite of di (2-ethylhexyl) phthalate (plasticizer used in plyvinyl chloride products) in humans.

4-Heptanone is a common volatile constituent of human urine and is of unknown origin. We hypothesised that it arises from in vivo beta-oxidation of 2-ethylhexanoic acid (EHA) from plasticisers, similar to formation of 3-heptanone from valproic acid. We investigated urine
