Descrição geral

4-Heptanone is a volatile constituent of human urine[1].

Aplicação

4-Heptanone was used in the quantitative analysis of 4-Heptanone in urine samples by gas chromatography-mass spectrometry[2]. 4-Heptanone was used to evaluate the enantioselectivity and catalytic ability of the 4-hydroxyacetophenone monooxygenase from Pseudomonas fluorescens ACB[3].

Ações bioquímicas/fisiológicas

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

The 4-hydroxyacetophenone monooxygenase (HAPMO) from Pseudomonas fluorescens ACB catalyzes NADPH- and oxygen-dependent Baeyer-Villiger oxidation of 4-hydroxyacetophenone to the corresponding acetate ester. Using the purified enzyme from recombinant Escherichia coli, we found that a broad range of carbonylic compounds that are

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
