How Food Works - Protein A protein is any chain of amino acids. An amino acid is a small molecule that acts as the building block of any cell. Carbohydrates provide cells with energy, while amino acids provide cells with the building material they need to grow and maintain their structure. Your body is about 20% protein by weight. It is about 60% water. Most of the rest of your body is composed of minerals (for example, calcium in your bones).
What's In Your Food - Protein Proteins form the body's main structural elements and are found in every cell and tissue. Your body uses proteins for growth and to build and repair bone, muscles, connective tissue, skin, internal organs and blood.
