Question

Where does the water present in the egg go after boiling the egg?

Answer 1

We should know that the denaturation of proteins involves the breaking of many weak linkages or bonds within a protein molecule that are responsible for the structure of the protein in its nature.

Complete answer:
We can say that after boiling the egg the denaturation of protein is happening. When we boil an egg in water, what happens is that the globular proteins in it change to a rubber like insoluble mass which absorbs all the water present in the egg by making hydrogen bond with it. Here, the denaturation of protein is the coagulation of albumin present in the white of an egg. On a detailed note of this process we may explain as when we boil an egg, the proteins inside them undergo denaturation. As we said denaturation is defined as when we have proteins of secondary or tertiary structures then they are destroyed while denaturation and remain only with primary structure. So, when we boil the egg, what happens is that the temperature gets increased which favours our denaturation. So, after denaturation, our proteins start coagulating. In this time our water gets absorbed or adsorbed. This is the reason why we do not see water after boiling the egg.

Note:
There are a lot of processes in denaturation of proteins. What we saw here is heating, apart from this exposure to acids or bases and even violent physical action can cause the denaturation. What we saw while boiling an egg the same thing happens by the violent physical action of an egg beater in the preparation of meringue. Keep in mind that most of the denaturation processes are irreversible.
