About this database
Peptide Biologix compiles publicly available physicochemical data and primary-literature citations for therapeutic peptides under active investigation. All molecular weights are reported as monoisotopic where indicated, otherwise as average molecular mass. CAS numbers reflect the most commonly cited registry entry for the free peptide unless noted otherwise. Where multiple synonyms exist, the most frequently used trade/research name is presented first. Compiled by Dr. Marius Kohler, Peptide Chemistry Group.
