The production of C¹⁴O₂ metabolized from glucose labeled in
specific carbon atoms by homogenates of chick embryonic and adult
heart was compared by the radiorespirometric technique. Homogenates
of early (two to five days of incubation) embryo hearts were
found to utilize the phosphogluconate pathway of glucose catabolism
to a greater...
Graphite oxides which had been prepared from three different
size graphite particles by the modified Brodie method were observed
with the electron microscope. The thermal decomposition products
of the oxides, obtained by heating them at 240° and 300°,
were observed using the electron microscope and x-ray diffraction.
Graphite oxide was...
Levels of activity of glucose-6-phosphate- , 6-phosphogluconate- , and isocitric- dehydrogenase were measured in the
soluble and particulate fractions of heart, brain and liver at
several ages throughout the development of the chick embryo.
Compared to isocitric dehydrogenase, levels of glucosesphosphate-
, and 6-phosphogluconate- dehydrogenase are generally
low. This suggests...
The investigation
of impurity effects on the properties of alkali
halide crystals has often been difficult because of the variation of procedures used in various experiments.
The purpose of this work is to
develop a self consistent method of measuring the IV dipole polarization properties of single crystals while eliminating...
