Benchling Aa Monomer API
An amino acid monomer is a building block for modified peptide sequences. Each AA monomer has a symbol identifier, chemical structure (SMILES/molfile), molecular weight, and attachment points defining where it bonds to other monomers. The naturalAnalog field links modified monomers to their standard amino acid counterpart (e.g., a modified alanine analog links to natural 'A'). AA monomers define the chemistry of non-standard amino acids used in peptide and protein engineering.
