Enzymes involved in acetoacetate formation in various bovine tissues.
1. The activities of acetoacetyl-CoA thiolase, hydroxymethylglutaryl-CoA synthase and lyase and acetoacetyl-CoA deacylase were measured in homogenates of samples of liver, rumen epithelium (long papillae), kidney and lactating mammary gland derived from slaughtered cows. 2. The activities of the four enzymes in bovine liver were similar to the activities previously reported for the correspondin...
متن کاملAcetoacetate Formation in Liver
In 1944, Weinhouse et al. (1) reported that the incubation of carboxyllabeled octanoate with rat liver slices yielded acetoacetate in which the carboxyl and carbonyl carbons were equally labeled. Random condensation of 2-carbon units resulting from ,8 oxidation was therefore offered by these workers as a possible mechanism for the formation of acetoacetic acid from octanoate. The conversion of ...
متن کاملThe formation of acetoacetate in homogenates of the mammary gland.
H. A. KREBS, P. K. JENSEN AND L. V. EGGLESTON I958 3. Adenosine 5'-phosphate, L-aspartate, L-asparagine, fumarate and glycerol each stimulated 'factor' activity but had no effect on the enzymic hydrolysis ofcarbamyl phosphate. This stimulation generally increased with time. 4. Some characteristics ofthe bacterial hydrolysis of carbamyl phosphate are described. 5. The results indicate that the b...
متن کاملFatty acid metabolism; conversion of acetoacetate to citrate in animal tissues, studied with isotopic carbon.
In Paper V of this series (1) it was found that the citrate which accumulates during the oxidation of W-tagged acetoacetate by rat kidney in the presence of oxalacetate had a high content of isotopic carbon, thus confirming the participation of tricarboxylic acids in the oxidation of fatty acid intermediates. The present study represents a continuation of the investigation of this reaction with...
متن کاملActivities of enzymes involved in acetoacetate utilization in adult mammalian tissues.
1. The activities in rat tissues of 3-oxo acid CoA-transferase (the first enzyme involved in acetoacetate utilization) were found to be highest in kidney and heart. In submaxillary and adrenal glands the activities were about one-quarter of those in kidney and heart. In brain it was about one-tenth and was less in lung, spleen, skeletal muscle and epididymal fat. No activity was detectable in l...
