TL;DR: In this paper, the reliability of the various Somogyi-Shaffer-Hartmann (SHH) copper reagents for glucose determination in biological material has been established, which can be accomplished by omission of the iodide and iodate in their preparation, since these interfere with the molybdate color reagents.

TL;DR: The use of diacetylmonoxime, CHs+ C:NOH, in strongly acid solution (trichloroacetic) as a reagent for the calorimetric determination of citrulline, a reddish yellow peach shade, was introduced.

TL;DR: The present investigation deals with the interrelationship of purines, pyrimidines, and creatine and their possible function as precursors for nucleoproteins and the values obtained suggest that nucleic acids are synthesized even more rapidly than proteins.

TL;DR: The method of Reinhold and Wilson is adapted for the photoelectric filter photometer for the determination of cholic acid in pure solutions and in bile with an accuracy approaching the maximum that can be attained with the visual color comparator.

TL;DR: An ornithine cycle similar to that proposed by Krebs and Henseleit as occurring in mammalian liver is demonstrated in Neurospora crassa, and to assign various steps in the cycle to the influence of particular single genes.

TL;DR: In this paper, it was shown that the transfer of the phospholyl group between acetic and adenylic acid was reversible, and this transfer was found to be reversible through the use of acetyl phosphate as the intermediary.

TL;DR: The present communication deals with the properties of an enzyme of Proteus vulgaris which catalyzes the oxidation of some eleven amino acids to their corresponding keto acids with liberation of ammonia both in the intact bacterial cell and in cell-free extracts.
