Relative Concentrations of N15 in Urinary Ammonia N and Urea N after Feeding N15-labeled Compounds
Available data on the isotopic ratio See PDF for Equation of ammonia (r(a)) and that of urea (r(u)) after a single feeding of glycine, aspartic acid, and ammonium citrate are analyzed. From this analysis the following conclusions are drawn. 1. The isotopic ratio See PDF for Equation of ammonia (r(a)) is always higher than that of urea (r(u)) in the initial period after a single feeding of isoto...
متن کاملRATE OF EXCRETION OF N15 AFTER FEEDING N15-LABELED l-ASPARTIC ACID IN MAN
1. l-Aspartic acid labeled with N(15) was fed to one human adult and six infants, and the total N and N(15) were determined in the urine from time to time. 2. The N(15) concentration (or isotopic ratio) of urinary N reached its maximum in the adult about 2 hours and in the infants about 4 hours after feeding, then fell off logarithmically. 3. Assuming that the N of aspartic acid readily entered...
متن کاملUptake of Glycine-n15 by Components of Cell Nuclei
1. The uptake of glycine-N(15) by components of cell nuclei was studied. The nuclear components were derived both from tissues with high metabolic rates-mammalian liver, kidney, and pancreas-and from cells with relatively low rates of metabolism-avian erythrocytes and echinoderm sperm. N(15) uptake by nuclear components of liver, kidney, and pancreas was far more rapid than by those of erythroc...
متن کاملGenomic sequence and analysis of the atypical temperate bacteriophage N15.
N15 is a temperate bacteriophage that forms stable lysogens in Escherichia coli. While its virion is morphologically very similar to phage lambda and its close relatives, it is unusual in that the prophage form replicates autonomously as a linear DNA molecule with closed hairpin telomeres. Here, we describe the genomic architecture of N15, and its global pattern of gene expression, which reveal...
متن کاملپراکندگی کشسان یونهای N15 توسط C12 درMeV 23
Scattering of 15N ions with the energy of Elab = 23 MeV on the CH2(Au) target is investigated. Elastic scattering of these ions in the angular range of 7°-19° was measured by employing the silicon strip detector, “LEDA”. Using the measured scattering data, deviation of ion beam, number of incident ions on the target and differential cross sections of the 12C(15N, 15N)12C elastic scattering in ...
