In the amino acid shown at the right, the amino group is shown in blue and the acid group is shown in red. The building blocks are called amino acids. For a structural protein, the dimensions and rigidity of the structure must be suited to its function.Ĭonsidering this complexity, proteins are made up of combinations of (usually) only 20 building blocks comprised of (usually) only 5 different elements. For a membrane protein, the protein must expose a hydrophobic core that will align with the hydrophobic membrane it resides in. For an enzyme, the protein must recognize and bind to a substrate molecule in a way that is favorable to the desired chemical reaction. The shape of a protein is essential to its function.
