General description
Urea is a colourless organic compound, without any odour. It is easily soluble in water.
Application
Utilizada para la desnaturalización de proteínas y como suave agente de solubilización para las proteínas insolubles o desnaturalizadas. Útil para la renaturalización de proteínas de muestras ya desnaturalizadas con cloruro de guanidina 6 M como los cuerpos de inclusión. Puede utilizarse con clorhidrato de guanidina y ditiotreitol (DTT) en el repliegue de las proteínas desnaturalizadas a su forma nativa o activa.
Urea has been used:
- to adjust the urea nitrogen concentration to a preferred range in blood reservoir for evaluating the dialyzer urea clearance
- to prepare standards to measure urea synthesis
- to prepare standards for blood urea nitrogen assay
Biochem/physiol Actions
Urea participates in the metabolism of nitrogenous substances. It serves as a nitrogen source, when used in fertilizers. Urea is used in manufacturing chemical compounds. It is widely used in the agricultural industry as a fertilizer as well as an animal feed additive, which is used as a nitrogen supplement in animal husbandry. Urea has adverse effects on seed germination, seedling growth and early plant growth in soil.
