Week 4 Draft 1

The difference between something that is cooked, and raw depends on the state of the protein. When something is cooked, proteins inside the cell are denatured from the proteins. Heat is a major component used to denature proteins to change the physical state of a compound. Because heat is usually released into the environment, it is almost impossible to renature a cell because the lost heat cannot be absorbed again. However, UC Irvine found a new approach to renature a protein to reverse the direction of the physical state. Urea, a chemical used for renaturation is a compound found in livers, that are soluble and produce ammonia to deaminate amino acids in the body. It is a waste product, but the characteristics of urea allows the denatured protein to renature.
