The Respiratory C14 Pattern of Acetate-1-C14 Oxidation in the Bovine

A comparison of the oxidation of octanoate-1-C14, -7-C14, and butyrate-1-C14 by neoplastic and normal mouse tissues.

The degradation of fatty acids of the even series by animal tissues yields Ca fragments (metabolically, acetyl-S-CoA) which may undergo various condensation reactions. Condensation with oxalacetate to form citrate is the established mecha nism for entrance of €2fragments into the tricarboxylic acid cycle, where they are subsequently oxidized to COs (11, 17). Liver possesses the abil ity to fo...

Incorporation of Acetate-1-c14 into Lipid by Typhus Rickettsiae'

Although it has been known for some time that rickettsiae have an independent, if limited, oxidative metabolism (Bovarnick and Snyder, 1949), evidence of any synthetic activity on the part of these organisms has until recently been lacking. It was noted (Bovarnick, 1956) that they were capable through oxidative phosphorylation of forming ATP,2 a compound that appears to be a prerequisite for al...

The metabolism of ascorbic acid-1-C14 and oxalic acid-C14 in the rat.

It is known that oxalic acid is a product of ascorbic acid metabolism in the guinea pig (1) and rat (2), and is formed in man from unidentified precursors (3). Oxalates are also of interest because of their occasional toxicity and unexplained deposition. Ascorbic, dehydroascorbic, and 2,3diketogulonic acids are known to give rise to oxalic and threonic acids in approximately quantitative yields...

Preparation of 1-C14-propene-1 and the mechanism of permanganate oxidation of propene.

. l-C14_propene~1 has been prepared. The migration of the double bond under a variety of experimental conditions in the preparation of propene has been investigated. 'rhe mechanism of the permanganate oxidation of the labelled propene has been examined; it has been found to proceed by several paths, the relative importance of which depends upon the experimental conditions .. especia lly the pH....
