Novel collagen mimics are disclosed with a tripeptide unit having the formula (Xaa-Yaa-Gly)
n
, where one of the positions Xaa or Yaa is a bulky, non-electron withdrawing proline derivative. By substituting a proline derivative at either the Xaa or Yaa position in the native collagen helix, the stability of the helix is increased due solely to steric effects relative to prior known collagen-related triple helices. Methods are also disclosed for making the novel collagen mimics.
