In chemistry, a zwitterion (/ˈtsvɪtəˌraɪən/ TSVIT-ə-rye-ən; from German Zwitter [ˈtsvɪtɐ] 'hermaphrodite'), also called an inner salt or dipolar ion, is...

A quinonoid zwitterion is a mesoionic zwitterion based on quinone-related chemical compounds. The benzene derivate 1,3-dihydroxy-4,6-diaminobenzene is...

acid CH3COOH. Zwitterions contain an anionic and a cationic centre in the same molecule, but are not considered salts. Examples of zwitterions are amino acids...

A Criegee intermediate (also called a Criegee zwitterion or Criegee biradical) is a carbonyl oxide with two charge centers. These chemicals may react with...

carboxylic acid is mostly deprotonated, so that the predominant species is the zwitterion H3N+−RCH−COO−. The pH at which the average charge is zero is known as...

acidic water solutions, the molecule assumes an electrically neutral zwitterion structure −OOC−CH(NH+ 3)−(CH 2)2−COOH. It is encoded by the codons GAA...
