Protein could not exist without the proper combination of amino acids. To understand how vital amino acids are, you must understand how essential proteins are to life. It is protein that provides the structure of all living things. Each organism, from the tiniest microbe to the largest animal is composed of protein. And in its various forms, it is protein that participates in the vital chemical processes that enable us to sustain life.
Proteins are essential for the growth of bones.
Enzymes, hormones and genes are also comprised of various proteins. Next to water, protein makes up the greatest portion of our body weight. Consequently, it is easy to see why meeting our body's protein requirements is so important to good health. In order for protein to be complete, it must contain all of its particular amino acids. Amino acids may be linked together almost indefinitely to form more than 50,000 different proteins and 20,000 known enzymes.
