The amino acid code
Amino acid codes are based on the IUPAC nomenclature. Proteogenic amino acids are
represented by a three letters code (example: Ala). By default, the amino acid is in L form. For the D form, add a D
in front of the letter code, separated by a hyphen (example: D-Ala).
When a fonctional group (like methyl) is added to the amino acid,
the symbol of the group will be added to the three letters code. For example, methylated amino acids are represented by adding the Me symbol, separated by a hyphen
(example: Me-Lys).
Other monomers
Other monomers can be incorporated into peptides. For example, acid derivatives are encoded by their trivial name (their common name) and carbohydrates are encoded by their classical abbreviation (For example, Glc for glucose). For fatty acid the classical nomenclature is used (for example C16:1(9) means hexadecen-9-oic acid) and the modifiactions are added (for example C16:1(9)-OH(3) means that an hydroxyl group is added on the third carbon).
