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...
متن کاملIn vivo studies on incorporation of glycine-2-C14 into proteins and nucleic acid purines.
was incorporated into tumor protein less rapidly than into liver protein, and that over a period of time its concentration decreased more slowly in tumor. Although Griffin et al. (16) have studied the uptake of glycine-2-C14 by normal tissues and by azo dye-induced hepatomas in rats, they did not separate nucleic acids from proteins nor did they present their data in the form of a turnover stud...
متن کاملThe incorporation of C14-orotic acid into nucleic acid pyrimidines in vitro.
The incorporation in vivo of compounds labeled with N15 or Cl4 into the purines and pyrimidines of nucleic acid has been repeatedly demonstrated (e.g. (l-3)). W e wish to report observations on the incorporation of radioactive erotic acid in vitro into the pyrimidines of the nucleic acid of rat liver slices. It is believed that this procedure will readily permit the study of precursors of nucle...
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 کاملIn vivo incorporation of acetate-1-C14 into cholesterol and fatty acids following testosterone propionate administration.
• With the development of a wide variety of hypocholesterolemie agents, the hypercholesterolemia commonly associated with coronary and aortic atherosclerosis has assumed a position of paramount importance in the quest for some reliable means of preventing atherosclerosis. Though hypercholesterolemia in itself has not been indicated as the primary cause of atherosclerosis, indications are that i...
