values of torsion angles È and É show the presence of two type III 0 -turns, at the Á Z Phe 2 and Gly 3 residues, and Gly 3 and Á Z Phe 4 residues. All amino acids in the peptide are linked trans to each other. Two intramolecular N-HÁ Á ÁO hydrogen bonds, between CO and NH groups, stabilize -turns p

Á2H 2 O, adopts the type I -turn conformation for the Á Z Phe 2 -Gly 3 residues. It is stabilized by a 4 ! 1 intramolecular hydrogen bond between the Á E Phe 4 NH and Gly 1 CO groups. All the amino acid residues in the pentapeptide sequence are linked trans to each other. The crystal structure is st

## Abstract The effect of cooling down to 150 K on the structures of __α__- (s.g. __P__2~1~/__n__), __β__- (s.g. __P__2~1~), and __γ__- (s.g. __P__3~1~) polymorphs of glycine was studied by X-ray single-crystal diffraction. No polymorphic transformations were detected. Relative volume changes and t
