Spinach leaf (Spinacia oleracea L.) discs infiltrated with [(15)N]glycine were incubated at 25 degrees C in the light and in darkness for 0, 30, 60 and 90 minutes. The kinetics of (15)N-incorporation into glutamine, glutamate, asparagine, aspartate, and serine from [(15)N]glycine was determined. At the beginning of the experiment, just after infiltration (0 min incubation) serine, and the amido...

lowed by determination of radioactivity in respiratory COj, protein, lipids, organic acids, and free amino acids. The greatest quantitative and qualitative changes in asparagine metabolism were found in lymphosarcoma with leukemic blood picture. Chronic lymphocytic leukemia resembled the normal pattern with acute lymphocytic leukemia occupying an intermediate position. With pro gression of chro...

In the title compound, C(10)H(12)N(2)O(5)S, one of the sulfonyl O atoms is hydrogen bonded to the amido N atom of an adjacent mol-ecule. There is also a weak hydrogen-bonding inter-action between the other sulfonyl O atom and the secondary amino N atom. In addition, the amido O atom is also hydrogen bonded to a carboxyl O atom. These hydrogen-bonding inter-actions give rise to a layer structure...
