WebGlycine and Proline start secondary structures called beta turns. A beta turn is a turn in the primary structure, stabilized by hydrogen bonding. Because Proline has an odd, cyclic structure, when it forms peptide bonds, it induces a bend into the amino acid chain. I challenge you to draw the peptide chain with proline; you will see it.
