Metabolism of pyruvic acid-2-C14 and hydroxypyruvic acid-2-C14 in algae.
The metabolism of pyruvic acid in the light and dark by Scenedesmus has been examined with two aims: to study the relationship of its metabolism to that of the intermediates of C1402 fixation and to compare its metabolic fate with that of hydroxypyruvate. The metabolism of hydroxypyruvic acid was compared with that of C1402 fixation in order to ascertain whether it might be a photosynthetic int...
متن کاملStudies on fluorinated pyrimidines. III. The metabolism of 5-fluorouracil-2-C14 and 5-fluoroorotic-2-C14 acid in vivo.
As one of the initial steps towards the determi nation of the metabolism and mechanism of action of fluorinated pyrimidines, 5-fluorouracil and 5fluoroorotic acid were labeled with radiocarbon in the 2-carbon atom. We have previously reported briefly that fluorouracil is incorporated, as such, into the combined nucleic acids of mouse liver, spleen, and Ehrlich ascites cells (9). The present rep...
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 کاملMetabolism of L-ascorbic acid-1-C14 in man.
n-Ascorbic acid labeled with Cl4 has been utilized in studying the metabolism of this vitamin in rats (1, 2) and guinea pigs (3, 4). In both species there is considerable conversion of carboxyl-labeled n-ascorbic acid to CO2 and significant urinary excretion of labeled oxalate. The important nutritional role of n-ascorbic acid made it desirable to study the metabolism of the labeled vitamin in ...
متن کاملThe metabolism of C14-labeled ethylenediaminetetraacetic acid in the rat.
Interest in ethylenediaminetetraacetic acid (EDTA) arises from its ability to combine with metal ions to form water-soluble chelates. Several important biological applications have been made of this property. The material has been shown to be effective (a) in mobilizing radioactive elements such as Pu, Am, and Y from the skeleton (1, 2), (b) as a valuable therapeutic agent in the treatment of p...
