Rate of Association of S35 and C14 in Plasma Protein Fractions after Administration of Na2S35O4, Glycine-C14, or Glucose-C14

Conversion of DL-lactate-2-C14 or -3-C14 or pyruvate-2-C14 to blood glucose in humans: effects of diabetes, insulin, tolbutamide, and glucose load.

The incorporation of formate-C14, glycine-2-C14, adenine-4, 6-C14, and phosphate-P32 into nucleic acids.

nine labeled either with C'4 or N'5. Considerable controversy has developed as to which one of these tracer compounds gives an accurate measurement of the “relativeturnover-rate― of the nucleic acids. In order to determine the “absolute turnover rate― of the nucleic acids, it is necessary to know the specific activity of the immediate precursor of the nucleic acids. Since even the ident...

Metabolism of Coprostanol-c14 and Cholestanol-4-c14 in Man.

Plasma Protein Labeled with Lysine-ε-c14

The metabolism of homologous plasma proteins, labeled with lysine-epsilon-C(14), after oral administration to dogs has been investigated. The speed of the various processes involved is indicated by the maximum rate of C(14) O(2) excretion which is attained within 1 to 4 hours, the prompt appearance of protein activity in the plasma and disappearance of non-protein activity from it, both virtual...

Fermentation of glucose-C14 and xylose-C14 by various strains of Leuconostoc mesenteroides.
