The Science of Hard-Boiled Eggs
Eggs are rich in protein, they are the main components that are found underneath the eggshell. The egg white has about 12% of protein and egg yolk has about 16% of protein. The protein is made up of a chain of amino acids. When eggs are in their native state, these amino acids are folded in such a way that it gives the protein its shape. So if there is any change made to the structure of the proteins, the structure of the entire egg may change. Some parts of the eggs are hydrophilic and some are hydrophobic so they are present inside the proteins. They keep the protein in shape but once it is heated the process of denaturation happens in which the heat disrupts the proteins and causes the egg to harden.
