Urea's high aqueous solubility reflects its ability to engage in extensive hydrogen bonding with water. By virtue of its tendency to form porous frameworks, urea has the ability to trap many organic compounds.

Does anybody know how urea behaves when it is dissolved in water without any addition of enyzme urease? Is it just solvated by H2O molecules (hydration) and no reaction takes places or is it ...

Instead of using ammonia in its gas phase, it is introduced to the system in the form of a urea-water-solution (UWS) through an injection nozzle.

Urea/water is an archetypical “biological” mixture, and is especially well known for its relevance to protein thermodynamics, as urea acts as a protein denaturant at high concentration. This behavior has given rise to an extended debate concerning urea’s influence on water structure.

Apr 24, 2017 · Urea is found in the urine or uric acid of most living organisms, and is written as chemical formula (NH2)2CO. This compound is highly soluble in water, due to its extensive hydrogen bonding.

It is found that urea incorporates readily into water, forming pronounced hydrogen bonds with water at both the amine and carbonyl headgroups. In addition the urea also hydrogen bonds to itself, forming chains or clusters consisting of up to approximately 60 urea molecules in a cluster.

Jan 17, 2024 · The team’s findings could help use urea in waste streams to efficiently produce hydrogen fuel through the electrolysis process, and could be used to sequester urea from water, maintaining the long-term sustainability of ecological systems, and …

Mar 17, 2024 · In this work, new experimental data on water activity for solutions containing urea under precisely controlled conditions and derived thermodynamic parameters were reported. Water activity of urea was also estimated from the Kirkwood–Buff integrals in a novel way.

Jan 11, 2021 · In addition to its high nitrogen content, urea is particularly useful because it can be applied as a solid in pellet form; and its unusually high solubility in water allows it to be incorporated into solutions with other plant nutrients. More …

Urea is used for many applications, e.g., in the development of pharmaceuticals and for manufacturing fertilizers. As a solid form, urea has a low moisture content (usually <0.25 wt%).
