4 molecules of water are formed when five amino acids are joined together.
Condensation reaction in amino acids
• A reaction in which two molecules combine to produce a single molecule is known as the condensation reaction.
• During the reaction, a small water molecule is generally removed.
• An essential biological molecules that possess an amine functional group on one terminal and a carboxylic acid functional group on the other terminal is known as the amino acid.
• In a condensation reaction, when two amino acids combine, formation of a covalent bond takes place between the amine nitrogen of one amino acid and the carboxyl carbon of the second amino acid. In the reaction, a molecule of water is removed as a second product.
Thus, when five amino acids are joined together, in total 4 molecules of water are released as a second product.
