The conversion of citrulline to arginine in kidney [PDF]

open access: yes, 1941
Glycocyamine is formed in the kidney by the transfer of the amidine group of arginine to the nitrogen atom of glycine. In the study of this reaction it was observed that glycocyamine was also formed from citrulline and glycine.

The conversion of L-histidine to glutamic acid by liver enzymes [PDF]

open access: yes, 1952
Edlbacher and Neber (1) showed in 1934 that the liver enzyme named histidase degrades histidine to NH3, formic acid, and an unknown product which on further treatment with strong alkali yields glutamic acid.

The free energies of formation of aqueous d-alanine, l-aspartic acid, and d-glutamic acid [PDF]

open access: yes, 1933
The employment of thermodynamics in biochemistry has been restricted, until recently, to the use of first law data. In the last few years a beginning has been made in the application of the second law; i.e., of free energy data (1, 2). The development of
