Amino Acids Table

Here is a list of the standard one-letter amino acid codes and their three-letter equivalents. The synonymous codons and their depiction in the IUB codes are shown. You should recognize that the codons following semicolons ( are not sufficiently specific to define a single amino acid even though they represent the best possible backtranslation into the IUB codes!
