Corned beef is a processed meat because it is cured through the curing brine. The brine contains both salt and usually a type of pink curing salt which contains sodium nitrite. The pink curing salt is what makes the corned beef a pink color.
Urea or carbamide is an organic compound with the chemical formula C O (N H 2) 2.The molecule has two âNH 2 groups joined by a carbonyl (C=O) functional group.rea serves an important role in the metabolism of nitrogen-containing compounds by animals, and is the main nitrogen-containing substance in the urine of mammals. It is colorless, odorless solid, highly soluble in water, and practically non-toxic (LD50 is 15 g/kg for rats).
Urea has very similar geometry, and electronegativity, to the Peptide bond-- a protein is made up of as many peptide bonds as there are amino acids (minus one), so you can use urea to essentially first interchelate between adjacent peptide bonds until complete denaturation.
