Protein is a class of organic compound that considered to be the building block of life. All living organisms have proteins, which are long chains of amino acids. The other types of organic compounds essential for life are carbohydrates and fats. When you eat food to sustain your life, you consume all three of these very important types of food.

Protein is found in large quantities in such things as: meat, dairy, eggs, fish, legumes, and soy products.

It is generally recommended that at each meal, there should be at least a small quantity of protein, since proteins are an essential ingredient in a healthy body.

Protein isn't exactly a type of anything. There are ,however, different types of protein such as, enzymes and structural protein (e.g. actin for the cytoskeleton)

Proteins are built up of long polypeptide chains of amino acids joined together by ester bonds. The type of protein produced is dependant on the kinds of amino acids it contains.
