Preferred Label : zwitterionic compounds/zwitterions;
IUPAC definition : Neutral compounds having formal unit electrical charges of opposite sign. Some chemists
restrict the term to compounds with the charges on non-adjacent atoms. Sometimes referred
to as inner salts, dipolar ions (a misnomer). E.g. H sub 3 /sub N sup class plus
/sup CH sub 2 /sub C( O)O sup class minus /sup ammonioacetate (glycine), (CH sub
3 /sub ) sub 3 /sub N sup class plus /sup –O sup class minus /sup trimethylamine
oxide.;
