Proteins are essential to the body. Protein builds up, maintains and replaces or restores the tissues and organs. Our muscles, organs, and our immune system are made up of protein. Our body uses the protein that we eat to make lots of specialized protein molecules that have specific jobs. For example, our body uses protein to make hemoglobin, the part of the RBC's ( Red Blood Cells) that carries O2 to every part of the body. I hope that this is useful. Here's a great website and it is easy to understand.
