A system of symbols for the amino acid residues of proteins and peptides is proposed. The symbols convey immediate meaning in chemical terms and therefore allow rapid recognition of the distribution and frequency of occurrence of the various functional groups. The system is readily adaptable to description of new amino acids and amino acid modifications.
