You’ll also see how dehydration reactions differ from a broader class of reactions called condensation reactions. Dehydration can lead to serious complications, including: Heat injury. The process of hydrolysis is the reverse reaction, meaning that the water is recombined with the two hydroxyl groups and the disaccharide reverts to being monosaccharides. Figure \(\PageIndex{1}\): A dehydration synthesis reaction involving ionized monomers. In organic synthesis, there are many examples of dehydration reaction, for example dehydration of alcohols or sugars. In the related condensation reaction water is released from two different reactants. condensation reaction a reaction involving the removal of water (dehydration) from two or more small molecules to form a new larger compound. For example, two monomers may react where a hydrogen (H) from one monomer binds to a hydroxyl group (OH) from the other monomer to form a dimer and a water molecule (H 2 O). The classic example of a dehydration reaction is the Fischer esterification, which involves treating a carboxylic acid with an alcohol in the presence of a dehydrating agent: Two monosaccharides, such as glucose and fructose, can be joined together (to form saccharose) using dehydration synthesis.
