In the illustration below, the blue squiggly line represents a protein. Notice that the amino acid that is colored red and the amino acid that is colored black are very close to each other in space, but they are far from each other in the primary structure of this protein. How can you explain why two amino acids that are so far from each other in the primary structure of a protein can be so close together in the tertiary structure of the same protein?
