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...

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...

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

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...

compound with the formula H3NC6H4SO3. It is an off-white solid. It is a zwitterion, which explains its high melting point. It is a common building block...

structure. Contributing structures containing charged atoms are denoted as zwitterions. Some dipolar compounds can have an uncharged canonical form. 1,2-dipolar...

it adopts an amide-like configuration. It is also commonly shown as a zwitterion. Muscimol can be extracted from the flesh of the Amanita muscaria by treatment...

100% of the analytical glycine concentration. Glycine may exist as a zwitterion at the isoelectric point, but the equilibrium constant for the isomerization...

acid with the formula (CH2SCH2NHCH)CO2H, although it crystallizes as the zwitterion (CH2SCH2NH+2CH)CO−2. It consists of a 1,3-thiazolidine ring ( (CH2SCH2NHCH2))...

is encoded by the codon UGG. Like other amino acids, tryptophan is a zwitterion at physiological pH where the amino group is protonated (–NH+ 3; pKa =...

formula NH2‐CH2‐COOH. In solution or in the solid, glycine exists as the zwitterion. Glycine is one of the proteinogenic amino acids. It is encoded by all...

corresponding carbonyl oxide (also called the Criegee intermediate or Criegee zwitterion) and aldehyde or ketone (3) in a retro-1,3-dipolar cycloaddition. The...

known as a dianion and an ion with a +2 charge is known as a dication. A zwitterion is a neutral molecule with positive and negative charges at different...

acid with the formula CH3N(H)CH2CO2H. It exists at neutral pH as the zwitterion CH3N+(H)2CH2CO2−, which can be obtained as a white, water-soluble powder...

carrier family, subfamily 22. This family of proteins can also transport zwitterions and anions, though it is a different subfamily of solute carrier proteins...

proteins. This shifts the proton more than two atoms away, producing a zwitterion rather than shifting a double bond: H2N−CH2−COOH ⇌ H3N+−CH2−CO−2 phosphite...

other amino acids (not as a residue of a protein), cysteine exists as a zwitterion. Cysteine has l chirality in the older d/l notation based on homology...
