When it is desirable to mention or emphasize the particular ionic form of a residue, this may be done as follows
Name of residue Protonated Form Deprotonated form arginine residue argininium residue arginine (base) residue histidine residue histidinium residue histidine (base) residue lysine residue lysinium residue lysine (base) residue aspartic residue aspartic (acid) residue aspartate residue cysteine residue cysteine (acid) residue cysteinate residue glutamic residue glutamic (acid) residue glutamate residue tyrosine residue tyrosine (acid) residue tyrosinate residueThis system cannot easily be applied to N- or C-terminal residues.
