Difference Between Dehydration Synthesis and Hydrolysis | Definition, Mechanism, Examples
What is the difference between Dehydration Synthesis and Hydrolysis? Dehydration synthesis reaction forms a water molecule; hydrolysis. Dehydration synthesis is like the opposite of hydrolysis. A peptide bond forms after a reaction between the carboxyl group of one amino acid and the amino. Chemistry. Learn vocabulary, terms, and more with flashcards, games, and other study tools. 3) Describe the difference between dehydration synthesis and hydrolysis 4) What is a given reaction as dehydration synthesis and hydrolysis?.
This linkage is formed by reaction of —OH groups of two monomer units with the elimination of water molecule. Formation of maltose is an example of dehydration synthesis reaction. Two alpha-glucose units form glycosidic linkage with elimination of water molecule to form one maltose molecule.
So we can say that a dehydration synthesis always involve two steps. Formation of a new product Loss of water molecule Back to Top Dehydration synthesis involves the formation of new chemical bonds between two molecules which leads the formation of new compound.
Reaction occurs with the loss of water molecule at each step.
It is also called as condensation reaction. Polymerization reactions are good examples of dehydration synthesis reaction in which monomer units condense together to form polymer. Formation of disaccharides from monosaccharides in carbohydrates, formation of lipids with one glycerol and three molecules of fatty acids are examples of dehydration synthesis. Similarly formation of nucleic acid from nucleotide is also an example of dehydration synthesis.
Hydrolysis can be considered as the reverse reaction of dehydration synthesis reaction.
Difference Between Hydrolysis and Dehydration Synthesis
It involves the addition of water molecule with cleavage of bonds to form more than one substance from one substance. In other words, hydrolysis is a chemical reaction which splits a molecule into smaller unites by the addition of water molecule.
For example hydrolysis of polymers results the formation of monomer units as it splits the connections between monomer units.
For example hydrolysis of disaccharide forms monosaccharide units. Similarly hydrolysis of lipids leads to formation of glycerol and fatty acids. What Happens in a Dehydration Synthesis Reaction? Back to Top Dehydration synthesis reactions are combination or synthesis reactions which occurs between same or different monomer units with elimination of water molecules.
However, this reaction consumes water molecules in order to provide —OH group for the carboxylic acid formation and the —H group for the alcohol formation. This process is called saponification.
Dehydration synthesis is the formation of a larger molecule with the release of water molecules.
Hydrolysis is cleavage of a chemical bond in the presence of water. Dehydration synthesis reactions are combination reactions.

Hydrolysis reactions are decomposition reactions. Dehydration synthesis reaction forms a water molecule. Hydrolysis reaction consumes a water molecule. The reactants of dehydration synthesis reactions are smaller molecules than their products.
The reactants of hydrolysis reactions are complex molecules than their products. Dehydration synthesis reactions give water molecules as byproducts. Hydrolysis reactions do not give byproducts. Conclusion Both dehydration synthesis and hydrolysis are chemical reactions that are occurred in the presence of water. Carbonyls Similarly, carbonyl groups in aldehydes and ketones usually increase polarity and reactivity of organic molecules.

Biomolecules containing carbonyls tend to be somewhat volatile, stimulating human senses with strong odors, both pleasant and unpleasant.
A carboxyl group contains both a carbonyl group and a hydroxyl group, bonded to the same carbon atom. With two oxygen atoms in this functional group, organic molecules containing carboxyl groups are often highly polar and reactive, although size and other functional groups present in an organic molecule are important in determining polarity and solubility. Traditionally, organic compounds containing carboxyl groups have been called carboxylic acids because of the tendency to release hydrogen ions into a solution lowering pH.
In general, amino groups increase polarity and reactivity of an organic molecule and readily form hydrogen bonds with water and other polar molecules. Like free ammonia NH3amines are weakly basic and bind to hydrogenions in solution raising pH.
