Question

Select true statements about the formation of a peptide bond:

A) Peptide bonds involve the sharing of electrons.
B) Water is a byproduct in the formation of a peptide bond.
C) Peptide bonds connect amino acids in a dehydration synthesis reaction.
D) Peptide bonds are broken through hydrolysis reactions.

Answer 1

The formation of a peptide bond involves the linking of amino acids through a dehydration synthesis reaction. Peptide bonds involve the sharing of electrons, water is a byproduct in their formation, and they connect amino acids in a dehydration synthesis reaction.

Step-by-step explanation:

The formation of a peptide bond involves the linking of amino acids through a dehydration synthesis reaction. During this process, the carboxyl group of one amino acid reacts with the amino group of another amino acid, resulting in the formation of a peptide bond and the release of a water molecule. Therefore, the statements that are true about the formation of a peptide bond are:

1. Peptide bonds involve the sharing of electrons.
2. Water is a byproduct in the formation of a peptide bond.
3. Peptide bonds connect amino acids in a dehydration synthesis reaction.

Peptide bonds are not broken through hydrolysis reactions; instead, they are broken through proteolysis, which involves the addition of water molecules to the peptide bond.
