Proteins act as a fuel source for the body. It is an important nutrient for humans as it contains the composition of amino acids. Like other nutrients such as lipids and carbohydrates, proteins are necessary to power up the body.
Proteins are the polymer chains linked by peptide bonds. While going through the process of digestion, proteins are broken down into smaller polypeptide chains with the help of hydrochloric acid and protease actions.
Proteins are available in our body in abundance. Meat, dairy, whole grains, eggs, soy, fish, tofu, and cereals are sources of protein.

Eggs are a versatile food product that can be used as an ingredient in cooking.
