Record Type: concept
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.
 
Terms:
urea (organic compound) (preferred,C,U,English-P,D,U,N)
carbamide (C,U,English,UF,U,U)
ureum (organische verbinding) (C,U,Dutch-P,D,U,U)

Additional Notes:
Dutch ..... Kleurloze, kristallijne organische verbinding die een product is van prote├»nemetabolisme 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.
