Which of the following reactions occurs when a dipeptide is formed from amino acids?
A
Hydrolysis
B
Denaturation
C
Condensation
D
Oxidation
Explanation: 

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. The name of this reaction is a result of the production of a water molecule that happens during this type of reaction.

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: -Two amino acids can react in a condensation reaction to form a peptide bond and release water. This forms a dipeptide. Many condensation reactions can occur between amino acids to build up a peptide or protein chain. Hydrolysis is the breaking of a bond by reacting with water.
