Proteins are macromolecular polypeptides i.e. very large molecules (macromolecules) composed of many peptide bonded amino acids. Most of the common ones contain more than 100 amino acids linked to each other in a long peptide chain. Amino acids although there are obviously many different kinds of proteins, they are all created from amino acids that are joined through the process of dehydration synthesis. As additional of the amino acids known as peptides are added, two amino acids combine to make dipeptides join together they form polypeptides. The quantity and kind of amino acids that make up the chain determine the length and complexity of proteins. There are around 20 different types of amino acids, and each one has a unique chemical makeup and set of properties.
