Appendix. Amino Acids with Trivial Names (excluding those listed in Table 1)

It is often helpful to use trivial names in order to avoid cumbersome systematic or semisystematic names, particularly if the substance has to be named frequently. Coining of trivial names is treated in 3AA-2.1, and a number of existing trivial names are listed in the appendices to the previous edition of recommendations on amino-acid nomenclature [6]; only the commoner are listed here.

 
 Trivial  Symbol  Structure of substance or of derived ion in the 
 name             form predominating at neutral pH  (Note i)
β-Alanine βAla NH3+-CH2-CH2-COO-

Allysine — HCO-[CH2]3-CH(NH3+)COO-

Citrulline Cit NH2-CO-NH-[CH2]3-CH(NH3+)COO-

Cystathionine

Note (i) Due to the limitations of the non-table format the above data is not in columns. In each row there is quoted in order the Trivial name, Symbol and Structure.
