Thr and/or Leu residues tend to disrupt an alpha helix when they occur next to each other in a protein because:

A D-amino acid would interrupt an alpha helix made of L-amino acids. Another naturally occurring hindrance to the formation of an alpha helix is the presence of:

The three-dimensional conformation of a protein may be strongly influenced by amino acid residues that are very far apart in sequence. This relationship is in contrast to secondary structure, where the amino acid residues are:
