- definition. Some
zwitterions, such as
amino acid
zwitterions, are in
chemical equilibrium with an
uncharged "parent" molecule.
Betaines are

influence of a
spatially uniform electric field. As a rule,
these are
zwitterions with a
positive or
negative net charge. Electrop****sis is used in laboratories...

Amphoteric or
zwitterionic detergents have
zwitterions within a
particular pH range, and
possess a net zero

- In
aqueous solution at pH
close to neutrality,
amino acids exist as
zwitterions, i.e. as
dipolar ions with both NH+3 and CO−2 in
charged states, so the...

Zwitterions contain an
anionic and a
cationic centre in the same molecule, but are not
considered salts.
Examples of
zwitterions are
amino acids...

Ylides are thus 1,2-dipolar compounds, and a
subclass of
zwitterions. They
appear in
organic chemistry as
reagents or
reactive intermediates...
