when you boil an egg the albumin is converted into a white solid mass. this phenomenon is

Answer 1

Eggs are rich in protein, especially the egg whites. It's this protein that causes eggs to become hard when boiled. Here's how it works:Protein is a chain of amino acids. These amino-acid strings fold back on themselves (the way the strings fold determines the protein's chemical and biological properties). The proteins are held in place by weak bonds (non-covalent) between different parts of the amino-acid string. When you break those strings, by various methods, you are denaturing the protein.

You can denature a protein in several different ways. Here are two ways to do it with eggs:

Heat - When you heat an egg, the proteins gain energy and literally shake apart the bonds between the parts of the amino-acid strings, causing the proteins to unfold. As the temperature increases, the proteins gain enough energy to form new, stronger bonds (covalent) with other protein molecules. When you boil an egg, the heat first breaks (unfolds) the proteins, and then allows the proteins to link to other proteins. As the proteins form these new, strong bonds, the water that surrounded each protein molecule when the egg was liquid is forced out. That's why the egg turns hard. (Heat affects all of the proteins in an egg, so it's the best way to cook an egg.)

Answer 2

Hey Dear,

◆ Answer -

Denaturation of proteins

● Denaturation of proteins -

• Phenomenon of destruction of secondary, tertiary and quaternary structure of proteins is called denaturation of proteins.
• Primary structure is conserved during proetin denaturation.
• Physical, chemical & biological properties of proteins change during the process.
• For example, when you boil an egg the albumin is converted into a white solid mass.
