Detailed explanation-1: -Answer and Explanation: The type of reaction that produces a dipeptide from two amino acids is called dehydration synthesis or a condensation reaction.

Detailed explanation-2: -A peptide bond is formed by a dehydration synthesis or reaction at a molecular level. This reaction is also known as a condensation reaction which usually occurs between amino acids. As depicted in the figure given below, two amino acids bond together to form a peptide bond by the dehydration synthesis.

Detailed explanation-3: -When two amino acids combine in a condensation reaction, a covalent bond forms between the amine nitrogen of one amino acid and the carboxyl carbon of the second amino acid. A molecule of water is then removed as a second product. Figure 25.18. 1: Amino acids join together to form a molecule called a dipeptide.

Detailed explanation-4: -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-5: -In organic chemistry, a condensation reaction is a type of chemical reaction in which two molecules are combined to form a single molecule, usually with the loss of a small molecule such as water. If water is lost, the reaction is also known as a dehydration synthesis.
