Potentiometric urea biosensors
Clinica Chimica Acta, 2022 Excess nitrogen in the body is converted to urea in the liver, and urea is disposed as a waste product in urine. Urea concentration can change in body fluids such as blood due to the presence of certain disorders. Therefore, the determination of urea is of high importance in various areas including medical diagnosis, as well as food quality control and

Urea-induced unfolding of rRsbW. [PDF]
, 2018 (A) The ellipticity values of rRsbW at 222 nm (θ222), were derived from their far-UV CD spectra (S1 Fig), normalized (Nor), and plotted versus the corresponding urea concentrations.

Aqueous Urea Solutions: Structure, Energetics, and Urea Aggregation [PDF]
The Journal of Physical Chemistry B, 2007 Urea is ubiquitously used as a protein denaturant. To study the structure and energetics of aqueous urea solutions, we have carried out molecular dynamics simulations for a wide range of urea concentrations and temperatures. The hydrogen bonds between urea and water were found to be significantly weaker than those between water molecules, which drives ...

Role of ureolytic activity in Bacillus cereus nitrogen metabolism and acid survival [PDF]
, 2008 The presence and activities of urease genes were investigated in 49 clinical, food, and environmental Bacillus cereus isolates. Ten strains were shown to have urease genes, with eight of these strains showing growth on urea as the sole nitrogen source ...

Hydration of urea and alkylated urea derivatives
The Journal of Chemical Physics, 2018 Compressibility data and broadband dielectric spectra of aqueous solutions of urea and some of its alkylated derivatives have been evaluated to yield their numbers Nh of hydration water molecules per molecule of solute. Nh values in a broad range of solute concentrations are discussed and are compared to hydration numbers of other relevant molecules ...
