Detailed explanation-1: -This reaction is also known as a condensation reaction which usually occurs between amino acids.

Detailed explanation-2: -Amino acids can be linked by a condensation reaction in which an ―OH is lost from the carboxyl group of one amino acid along with a hydrogen from the amino group of a second, forming a molecule of water and leaving the two amino acids linked via an amide-called, in this case, a peptide bond.

Detailed explanation-3: -Proteins are condensation polymers made from amino acids. An amino acid consists of a carbon atom (called the carbon, shown in red below) bonded to a hydrogen atom, an amine group, a carboxylic acid group, and an R group, often called the side chain .

Detailed explanation-4: -Proteins are formed in a condensation reaction when amino acid molecules join together and a water molecule is removed. The new bond formed in protein molecules where amino acids have joined (-CONH) is called an amide link or a peptide link.

Detailed explanation-5: -Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.
