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...
متن کاملThe 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...
متن کاملIncorporation 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...
متن کاملSynthesis of D-Glucose-1-C14 and D-Mannose-1-C14
Heretofore, radiochemical yields of sugars position-labeled with carbon-14 have been only 5 to 10 percent. This paper reports an improved cyanohydrin synthesis, and the preparation of D-glucose-1-C and D-mannose-1-C from D-arabinose in yields of about 50 percent. Low yields in prior syntheses appear to have been due to several inefficient steps, and to the fact that extension of the carbon chai...
متن کاملIncorporation of Sulfate-s35 and Glucosamine-1-c14 into Heparin during Perfusion of Isolated Rat Liver.
• The addition of sulfate-S" to rat blood perfusing an isolated, surviving rat liver causes association of some of the isotope with several plasma protein fractions x in a pattern similar to that obtained when the isotope is injected in a living rat. Preparative starch block electrophoresis (pH 8.6) of aliquots of the perfusing plasma indicates that approximately 80$ of the bound radioactivity ...
