Answer 1

The formation of the peptide bond

Explanation:

Option (a) Hydroxyl group is lost from its carboxyl group of one amino acid and a hydrogen atom is lost from its amino group of another  amino acid.

Peptide bond is the bond that connects two amino acids. It is called peptide bond because this bond is responsible for formation of protein polymer from amino acid monomer.

During peptide bond formation, removal of water molecule takes place, so it comes under the category of bond formation via condensation.

Formation of peptide bond:

1. carboxyl group of first amino acid provides hydroxyl group

2. amino group of second amino acid provides hydrogen

3. water is release and peptide bond forms.
