An unexpected way to reduce the cost of anti-cancer therapies has been discovered by researchers at the University of California at Irvine and the University of Western Australia.
With innovative technology, they have been able to prove that the process of cooking an egg is reversible. The scientific breakthrough was announced by the American edition MailOnline.
Scientists have succeeded in turning hard-boiled eggs into raw ones by dissolving the proteins with the help of the organic compound urea. The substance urea is contained in the urine. It is also possible to extract it artificially.
The chemical reaction in boiling an egg is the binding of proteins. This forms a solid mass. We've found a way to make a boiled hen's egg raw again, says Professor Gregory Weiss, a biochemist at the University of California, Irvine. In the scientific publication, we have described a method for separating bound proteins, the scientist added.
At the start of the experiment, the team boiled an egg for 20 minutes at a temperature of 90 degrees Celsius. Scientists have injected urea into the finished hard-boiled egg. In order for the urea to work, because in the initial phase the dissolved protein particles are still unusable, the scientists placed the liquid solution in a machine similar to a centrifuge. This helped the processes to reverse.
In the experimental technique, pressure was applied to the small particles, returning them to their original shape. The experiment is in its infancy, so it is not yet clear whether the egg can be consumed after returning it raw.
Scientists believe that the discovery, which allows for a quick and cheap return of protein to its original state, will make protein production easy, which, in turn, will reduce its production cost.
The widespread use of different types of protein in anti-cancer therapies is known, so this will reduce their value, explains Professor Weiss.
