Proteins control nearly every system in our bodies.
Antibodies, enzymes, and many hormones are proteins. A protein's three-dimensional structure determines which molecules it binds, which reactions it catalyzes, and, to some extent, where it is located in the cell. It is much easier to determine the order, or sequence, of amino acids in a protein than it is to determine the protein's three-dimensional structure. Although the sequence contains all the information necessary for correct folding, scientists still cannot predict a protein's final shape from its sequence. Then we might be able to do more about these disorders.
