Foldamers are chemical oligomers that mimic the structural behavior of natural peptides, and proteins by folding into well-defined 3D conformation in solution. FoldamerDB is the first public database of peptidic foldamers, created with the aim to gather and provide information related to their identification, experimental structure and biological activities. Links to databases like PDB, CCDC, PubMed, and NCBI are included for the benefit of users.
