The present work describes the synthesis and crystallographic analysis of γα hybrid peptides, Boc‐γ 4 ‐L‐Phe‐L‐Pro‐NHMe ( P1 ) and Boc‐(γ 4 ‐L‐Phe‐L‐Pro) 2 ‐NHMe ( P2 ). Peptide P1 adopts twelve membered (C 12 ) helical turn over γα segment, while P2 folds into twisted ribbon structure involving two expanded C 12 helical turns.
