Proteins are essential nutrients for the growth and proper functioning of the human body. They play a key role in building and repairing muscles and strengthening the immune system. Proteins are composed of chains of amino acids made up of hydrogen, carbon, oxygen, and nitrogen.

While proteins are commonly associated with food, they are also integral components of the human body. They are found in bones, organs, muscles, skin, cartilage, hair, nails, teeth, and more. In fact, every part of our body contains proteins, and each person has unique proteins based on their genetic makeup and biological needs.
