 Proteins make up about 15% of the mass of the average person. Protein molecules are essential to us in an enormous variety of different ways. Much of the fabric of our body is constructed from protein molecules. Muscle, cartilage, ligaments, skin and hair - these are all mainly protein materials.
In addition to these large scale structures that hold us together, smaller protein molecules play a vital role in keeping our body working properly. Haemoglobin, hormones, antibodies , and enzymes are all examples of these less obvious proteins.
Whether you are a vegetarian or a ? meat eater? you must have protein in your diet. The protein in the food we eat is our main source of the chemical building blocks we need to build our own protein molecules.
