The charged molecule which is electrically neutral is known as
1 amino acid
2 zwitterion
3 amide
4 peptide
Explanation:
(b) Zwitterion is a neutral molecule with a positive and a negative electrical charge, though multiple positive and negative charges can be present. Amino acids are the best known examples of zwitterions.

Which of the following shows zwitter ionic form?
1
2
3
4 None of these
Explanation:
(b)
Shows zwitter ionic form. Zwitter ions are those ions that are electrically neutral overall but contain non adjacent regions of positive and negative charges. They are sometimes referred to as dipolar ions. Free amino acid found in cells is an example of zwitterion. General structure of an amino acid exposes two parts, or groups, of the molecule that can function as an acid/base pair, the $-\text{COOH}$ and $-\text{N}{{\text{H}}_{2}}$ groups.
(d) Thiamine is nitrogen base. Acetic acid is a weak acid, Cytidylic acid is a nucleotide.
