A polynonapeptide of the formula: --X--(.alpha..beta..gamma..delta..epsilon..theta..lambda..pi..rho.).sub.n Y-- wherein: .alpha. is a peptide-forming residue of L-Valine or another peptide-forming residue capable of functioning in position i of a .beta.-turn in a polypeptide; .beta. is a peptide-forming residue of L-Proline or another peptide-forming residue capable of functioning in position i+1 of a .beta.-turn in a polypeptide; .gamma. is a peptide-forming residue of L-Glycine or another peptide-forming residue capable of functioning in position i+2 of a .beta.-turn in a polypeptide; .delta. is a peptide-forming residue of L-Phenylalanine or another peptide-forming residue capable of functioning in position i+3 of a .beta.-turn in a polypeptide; .epsilon. is a peptide-forming residue of Glycine, or D-Alanine, when functioning as position i' of a subsequent .beta.-turn in a polypeptide when .delta. is as defined, or .epsilon. is as defined for .alpha. when .delta. is Glycine or D-Alanine; .theta. is a peptide-forming residue of L-Valine, L-Alanine or another peptide-forming residue as defined above for .alpha., or when functioning as position (i+1)' of a subsequent .beta.-turn in a polypeptide, .theta. is a peptide-forming residue as defined above for .beta.; .lambda. is a peptide-forming residue of Glycine, D-Alanine or another peptide-forming residue as defined for .gamma., when functioning as position (i+2)' of a subsequent .beta.-turn in a polypeptide; .pi. is a peptide-forming residue of L-Alanine or another peptide-forming residue as defined for .delta., when functioning as position (i+3)' in a subsequent .beta.-turn in a polypeptide, or a direct bond; and .rho. is a peptide-forming residue of Glycine, or D-Alanine; wherein X is .beta..gamma..delta..epsilon..theta..lambda..pi..rho., .gamma..delta..epsilon..theta..lambda..pi..rho., .gamma..epsilon..theta..lambda..pi..rho., .epsilon..theta..lambda..pi..rho., .theta..lambda..pi..rho., .lambda..pi..rho., .pi..rho., .pi. or a direct bond; Y is .alpha..beta..gamma..delta..epsilon..theta..lambda..pi., .alpha..beta..gamma..delta..epsilon..theta..lambda., .alpha..beta..gamma..delta..epsilon..theta., .alpha..beta..gamma..delta..epsilon., .alpha..beta..gamma..delta., .alpha..beta..gamma., .alpha..beta., .alpha. or a direct bond; and n has a value of 1 to about 5,000, and with the proviso that no more than three or residues .epsilon., .theta., .lambda., .pi. and .rho. are simultaneously a peptide-forming residue of Glycine. The polynonapeptides have increased elastic moduli and exhibit chemotaxis toward fibroblasts and endothelial cells.
