Proteins are composed of amino acids, each of which have their own special properties. The nonpolar amino acids would fold into the interior of the protein during protein folding, because they are hydrophobic. A protein consists of a primary structure, which consists of the amino acid chain. The secondary structure is how the amino acids join together into alpha helixes and beta pleated chains and form hydrogen bonds. The tertiary structure is when disulfide bridges form, which maintain the protein's 3-d shape, and the 3-d shape begins to emerge. The quarternary structure is an assortment of several polypeptides, and constitutes the entire protein. The final shape of the protein determines its function.
