urea (organic compound) (organic compounds, compounds (materials), ... Materials (hierarchy name)) |
|
Note: A colorless crystalline organic compound that is a product of protein metabolism in mammals. Urea can break hydrogen bonds and destabilize collagen. In conservation practice, this interaction reduces hardness and deformation in parchment, leather, and related materials.

Additional Notes: |
|
| Dutch ..... Kleurloze, kristallijne organische verbinding die een product is van proteïnemetabolisme bij zoogdieren. Ureum kan waterstofbruggen afbreken en collageen destabiliseren. In de context van conservering vermindert deze interactie hardheid en vervorming in perkament, leer en verwante materialen.
