Similarly, loss of a proton from the ammonium cation of the zwitterion is
influenced by the electron-donating inductive effect from the carboxylate anion,
which should make the amino group more basic than a typical amine. That this is
not the ...

Such a structure, having both positive and negative charges on the same
molecule, is referred to as a zwitterion and can react as an acid, ÀOOCCH2

Principles and Techniques of Biochemistry and Molecular Biology
At a particular intermediate pH the amino acid carries no net charge, although it
is still ionised, and is called a zwitterion. It has been shown that, in the crystalline
state and in solution in water, amino acids exist predominantly as this zwitterionic

Chemistry: The Molecular Science
The term “zwitterion” is derived from the German word zwitter, meaning “a hybrid.
” one acidic carboxylic acid group and at least one basic amine group. An
intramolecular Brønsted-Lowry acid-base reaction occurs in amino acids in which
H is ...

Chemistry for Today: General, Organic, and Biochemistry
The zwitterion form has a net charge of 0, but the form in acid solution has a net
positive charge. When the pH of the solution is increased by adding OH2, the
iNH31 of the zwitterion can lose a proton, and the zwitterion is converted into a ...

Experience suggests the crucial zwitterion formation B Æ C might not be easy
since the charge separation that needs to occur might require too much energy.

The term ''zwitterion'' is a German word designating the presence of an ''inner salt'
' or an internal ionic species within a molecule. Most biochemistry textbooks
indicate that zwitterions are electrically neutral, lacking any overall net charge.

... if assay conditions change. Dilution is one such possible change. It is useful to
have a buffer that maintains a stable pH even if assay conditions change.
Temperature variation is one such possible change. The only zwitterion is 1H3N!
