Question

write about zwitter ion

Answer 1

Zwitterion is the dipolar form of an amino acid which occurs when H + ion is transferred from an acid group to an amine group. formerly called a dipolar ion, is a molecule with two or morefunctional groups, of which at least one has a positive and one has a negative electrical charge and the net charge of the entire molecule is zero. Because they contain at least one positive and one negative charge, zwitterions are also sometimes called inner salts.The charges on the different functional groups balance each other out, and the molecule as a whole is electrically neutral. The pH where this happens is known as theisoelectric point.

Unlike simple amphoteric compounds that may only form either a cationic or anionic species, a zwitterion simultaneously has both ionic states.

Answer 2

What is a Zwitterion?

Let's take the word zwitterion apart to figure out what it means. There's the -ion part at the end, which is a chemical species with a charge. The first part of the name comes from the German word 'zwitter', meaning hermaphrodite or hybrid. In other words, this term means half anion and half cation. Zwitterions are sometimes called dipolar ions, because they have a negative end (the anion) and a positive end (the cation).

Amino acids are the building blocks of proteins in living cells. They are compounds that contain an amino group and a carboxyl group. Twenty different amino acids are found in proteins. They share the structure shown here, where R represents one of the 20 possible side chains on an amino acid.



At neutral pH values, the amino group (-NH3+) has a positive charge and the carboxyl group (COO-) has a negative charge. Here is what the simplest amino acid, glycine, looks like in its zwitterion form.
