The book presents details on the ‘aliphatic foldamers', with a special emphasis on the peptides with – homogeneous backbones (ã- and ä-peptides), peptides with heterogeneous backbones (from alternating á-, â-, ã-, ä- and å-amino acids), peptides with backbone modifications (aminoxy-, hydrazine- and ureido peptides), peptides from sugar amino acids and methods for conformational analysis. The material presented in the book is useful for the research and student community to usher in a sustained propagation of this active area of research on ‘foldamers'.
