Proteins are defined by their unique sequence of amino acids (beads). In humans, the average protein is about 350 amino acids (beads) long. Some proteins are made up of many small repeating units (e.g. F-I-T-F-I-T-F-I-T… aka Phenylalanine-Isoleucine-Threonine…), while others have no repeating units
