Carboxylic Acids and their Derivatives
Amino Acids Rule C-421
421.1 - Table VIII gives examples of trivial names for -amino
carboxylic acids. The name of the radical obtained by removal of hydroxyl from the carboxyl group is derived from the trivial name of the amino acid by replacing the ending "-ine" with "-yl''.
421.2 - The following names are also recommended, the radical names being exceptions to the preceding rule:
421.3 - (a) 2-Aminobutanedioic acid is named aspartic acid. (b) 2-Aminopentanedioic acid is named glutamic acid. (c) The
derived univalent acyl radicals are named aspartyl and glutamyl, while the corresponding bivalent acyl radicals are named aspartoyl and glutamoyl (compare Rule C-403.1 and
C-405.2). (d) Monoamides of these acids in which the carboxyl group numbered I is intact are respectively named asparagine and glutamine, and univalent acyl radicals corresponding
to these monoacids are named asparaginyl and glutaminyl (see Table IX).
421.4 - The following trivial names are also retained:
