Molecular Design
Analyze real therapeutic peptides — D-amino acids, non-natural residues (Aib, Nal, pyroGlu), lipidation and terminal modifications. Get modification-aware mass, charge and pI, or an honest flag when a residue can't be resolved.
Dash-tokenized 3-letter, D/L chirality, terminal mods (NH2, Ac, NHEt) and plain 1-letter are all accepted.
Examples
Enter a sequence or modified notation to analyze.
Try one of the examples — including modified therapeutics that plain single-letter analyzers can't read.
