The entire molecule has a net neutral charge and is a zwitterion.

A betaine thus may be a specific type of zwitterion.

The solid acid exists as a zwitterion, and has an unusually high melting point.

Subsequent to this, radiationless decay leads to a zwitterion ground state.

If a surfactant contains a head with two oppositely charged groups, it is termed zwitterion.

The drugs, however, cannot move readily across the luminal membrane since it is a zwitterion.

This quaternary ammonium exists as the zwitterion at neutral pH.

This difference is attributed to them being dipolar ionic zwitterion compounds.

In fact in 2002 the compound was found to be more stable and to exist as the zwitterion after a proton transfer.

Homocysteine exists at neutral pH values as a zwitterion.

Neutron diffraction measurements show that solid sulfamic acid exists as a zwitterion.

Thienamycin is a zwitterion at pH 7.

The presence of an acid facilitates the elimination reaction in the zwitterion by proton transfer which becomes much faster and no longer rate determining.

The structures given below are standard chemical structures, not the typical zwitterion forms that exist in aqueous solutions.

It is a zwitterion, consisting of both a quaternary ammonium cation and a carboxylate.

Upon heating α-picolinic acid will spontaneously decarboxylate forming a zwitterion (2).

Zwitterion - is a chemical compound whose net charge is zero and hence is electrically neutral.

Since pyocyanin is a zwitterion at blood pH, it is easily able to cross the cell membrane.

This molecular state is known as a zwitterion, from the German Zwitter meaning hermaphrodite or hybrid.

The molecule tends to exist as a zwitterion where a phosphonic hydrogen dissociates and joins the amine group.

It is a zwitterion and an isomer of hydrogen cyanide (HCN).

It is a zwitterion formed by the methylation of the nitrogen atom of niacin (vitamin B).

Thus, it must be described either as zwitterion, or as the simplest conjugated hydrocarbon that cannot be given a Kekulé structure.

In the presence of a strong electrophile, such as an aldehyde, the zwitterion will react with the carbonyl faster than protonating.

As shown in the structural formula, MOED can exist in two resonance forms: A neutral molecule and a zwitterion.
