Facts about Protein

• Protein is a macronutrient that is essential to building muscle mass.
• It is commonly found in animal products, though is also present in other sources, such as nuts and legumes.
• Chemically, protein is composed of amino acids, which are organic compounds made of carbon, hydrogen, nitrogen, oxygen or sulfur.
•  Just as amino acids are the building blocks of proteins, proteins are the building blocks of muscle mass.
