X‐ray diffraction studies have been made on the polytripeptide poly( L ‐prolyl‐ L ‐α‐phenylglycyl‐ L ‐proline). Its structure has been found to be helical, with a poly( L ‐proline) II conformation, packed in an orthorhombic lattice, space group P2 1 2 1 2, with a = 14.3 Å, b = 13.5 Å, and c = 9.4 Å.
