Treatment of rabbits with 1% (v/v) acetone for 1 week resulted in the appearance in blood serum of 88 +/- 14 14 nmol/ml 1-hydroxyacetone (acetol) and 70 +/- 9 nmol/ml 1,2-propanediol. Untreated rabbits had no detectable 1,2-propanediol or acetol. Hepatic microsomes from control, ethanol-, and acetone-treated rabbits catalyzed the hydroxylation of acetone at rates of 0.32 +/- 0.01, 2.01 +/- 0.43...
Acetone degradation by cell suspensions of Desulfococcus biacutus was CO2 dependent, indicating initiation by a carboxylation reaction, while degradation of 3-hydroxybutyrate was not CO2 dependent. Growth on 3-hydroxybutyrate resulted in acetate accumulation in the medium at a ratio of 1 mol of acetate per mol of substrate degraded. In acetone-grown cultures no coenzyme A (CoA) transferase or C...
We apply a full year of continuous atmospheric acetone measurements from the University of Minnesota tall tower Trace Gas Observatory (KCMP tall tower; 244 m a.g.l.), with a 0.5× 0.667 GEOS-Chem nested grid simulation to develop quantitative new constraints on seasonal acetone sources over North America. Biogenic acetone emissions in the model are computed based on the MEGANv2.1 inventory. An i...
